gnu: commencement: Build Bison deterministically.

Before that entries in liby.a would contain the build time.

* gnu/packages/commencement.scm (bison-boot1): Add #:make-flags.

gnu: commencement: Build the final Bash with "bison-boot1".

This removes a round of Bison + Flex + M4 + Perl rebuild.

* gnu/packages/commencement.scm (bash-final): Add 'native-inputs'
field pointing to BISON-BOOT1.

gnu: commencement: Avoid redundant Perl rebuild.

This removes a redundant (yet different) "perl-boot0" node from the
early derivation graph.

* gnu/packages/commencement.scm (bison-boot1): Move 'native-inputs'
field to the final package.  Previously PERL-BOOT0 got rebuilt with
%BOOT0-INPUTS, leading to a different derivation.
(static-bash-for-glibc): Likewise.

gnu: commencement: Add "-boot0" to early packages.

* gnu/packages/commencement.scm (diffutils-boot0)[name]: New field.
* gnu/packages/commencement.scm (findutils-boot0, file-boot0,
perl-boot0): Change 'name' field to include "-boot0".

gnu: commencement: Use GMP 6.0.0a for bootstrapping.

* gnu/packages/multiprecision.scm (gmp-6.0): New variable.
* gnu/packages/commencement.scm (gcc-boot0, gcc-final): Use it.
* gnu/packages/patches/gmp-arm-asm-nothumb.patch: New file, reinstated
from before e414a7d.
* gnu-system.am (dist_patch_DATA): Add it.

gnu: grep: Add missing dependency on Perl.

* gnu/packages/base.scm (grep)[native-inputs]: New field.
* gnu/packages/commencement.scm (grep-final): Likewise.

gnu: commencement: Initial Texinfo uses initial Perl.

* gnu/packages/commencement.scm (texinfo-boot0)[inputs]: Use
PERL-BOOT0.

gnu: perl: Update to 5.22.0.

* gnu/packages/perl.scm (perl)[source]: Update to 5.22.0.  Remove
"perl-module-pluggable-search.patch" since Module::Pluggable appears to
be gone.
[arguments] <configure-phase>: Adjust Cwd.pm file name.  Replace
-std=c89 with -std=gnu89.
* gnu/packages/commencement.scm (perl-boot0): Add 'disable-pthreads'
phase.
* gnu/packages/patches/perl-no-sys-dirs.patch: Update.
* gnu/packages/patches/perl-module-pluggable-search.patch: Remove.
* gnu-system.am (dist_patch_DATA): Adjust accordingly.

gnu: gcc: Use the system zlib.

* gnu/packages/gcc.scm (gcc-4.7) <configure-flags>: Pass
'--with-system-zlib'.
* gnu/packages/commencement.scm (gcc-boot0)[arguments]: Remove
'--with-system-zlib' from the configure flags.
* gnu/packages/commencement.scm (zlib-final): New variable.
(gcc-final)[arguments]: Add ZLIB-FINAL to #:allowed-references.
Pass -L and -Wl,-rpath for zlib in LDFLAGS, as a configure flag.
[inputs]: Add LD-WRAPPER-BOOT3 and ZLIB-FINAL.

gnu: gcc-final: Remove unnecessary CPPFLAGS.

* gnu/packages/commencement.scm (gcc-final)[arguments]: Remove
unnecessary CPPFLAGS from #:make-flags.

gnu: commencement: Restrict allowed references for libstdc++.

* gnu/packages/commencement.scm (libstdc++)[arguments]: Add
  #:allowed-references.

Merge branch 'core-updates'

gnu: commencement: Remove the tricky locale compatibility handling.

This is made unnecessary by the use of 'GUIX_LOCPATH'.

* gnu/packages/commencement.scm (locale-proof-package): Remove.
  (%boot5-inputs): Add on GLIBC-UTF8-LOCALES-FINAL.  This reverts parts
  of commit 28cbc58.
* gnu/packages/gawk.scm (gawk): Set 'GUIX_LOCPATH' instead of
  'LOCPATH'.

Merge branch 'core-updates'

gnu: gcc-toolchain: Don't try to delete OUT/bin/sh, which no longer exists.

* gnu/packages/commencement.scm (gcc-toolchain)[arguments]: Remove code that
  deletes OUT/bin/sh and OUT/bin/bash, since those files no longer exist in
  our libc package.

gnu: coreutils-light: Rename to coreutils-minimal.

* gnu/packages/base.scm (coreutils-light): Rename to ...
  (coreutils-minimal): ...this.
* gnu/packages/commencement.scm (%boot5-inputs): Use it.

gnu: glibc: Upgrade to 2.22.

* gnu/packages/base.scm (glibc): Upgrade to 2.22.
  (coreutils-light): New variable.
* gnu/packages/commencement.scm (locale-proof-package): New procedure.
  (%boot5-inputs): Add LD-WRAPPER, BINUTILS-FINAL, BASH-FINAL, GNU-MAKE,
  DIFFUTILS, FINDUTILS, COREUTILS-LIGHT (pass through
  'new-libc-package'), and %BOOTSTRAP-COREUTILS&CO (passed through
  'locale-proof-package'.)

gnu: glibc: Do not copy static Bash binary to bin/.

This avoids problems when installing 'glibc' in a profile, where glibc's
limited 'bash' would take precedence over the valid 'bash'.

* gnu/packages/base.scm (glibc)[arguments]: Do not copy STATIC-BASH to
  OUT/bin.  Instead, simply refer to it directly.
  [inputs]: Use STATIC-BASH instead of BASH-LIGHT.
* gnu/packages/commencement.scm (static-bash-for-glibc): Likewise.
  (glibc-final)[arguments]: Add STATIC-BASH-FOR-GLIBC to
  #:allowed-references.
  (gcc-final)[arguments]: Likewise.
  [native-inputs]: Add "static-bash".

gnu: gcc-5.1, gcc-toolchain-5.1, libstdc++-doc-5.1: Rename to *-5.

This reflects the new version numbering scheme for GCC 5 and up.
See <https://gcc.gnu.org/develop.html>.

* gnu/packages/gcc.scm (gcc-5.1): Rename to ...
  (gcc-5): ... this.
  (libstdc++-doc-5.1): Rename to ...
  (libstdc++-doc-5): ... this, and use gcc-5.
* gnu/packages/commencement.scm (gcc-toolchain-5.1): Rename to ...
  (gcc-toolchain-5): ... this, and use gcc-5.
* build-aux/hydra/gnu-system.scm (%core-packages): Use gcc-5.
