Merge branch 'core-updates'.

Revert "build-system/gnu: Keep the sloppy conversion strategy during bootstrap."

This reverts commit b479c3ddaf85c831e34888229849bc1ce34419de.
This commit was the result of an incorrect characterization of the
problem; see the log of commit 87c8b92 for details.

build-system/gnu: Keep the sloppy conversion strategy during bootstrap.

* guix/build/gnu-build-system.scm (gnu-build): Leave
  %DEFAULT-PORT-CONVERSION-STRATEGY unchanged when 'string->bytevector'
  fails to convert to ISO-8859-1.  This is an attempt to work around the
  build failures at <http://hydra.gnu.org/build/263002>.

packages: Set the port conversion strategy to 'error'.

Suggested by Mark H Weaver.

* guix/build/gnu-build-system.scm (gnu-build): Set
  %DEFAULT-PORT-CONVERSION-STRATEGY to 'error.
* guix/packages.scm (patch-and-repack)[builder]: Likewise.

build-system/gnu: Set $LC_ALL (or similar) to the chosen locale.

Suggested by Mark H Weaver.

* guix/build/utils.scm (locale-category->string): New procedure.
* guix/build/gnu-build-system.scm (install-locale): Add 'setenv' call.

build-system/gnu: Add 'install-locale' phase.

* guix/build/gnu-build-system.scm (install-locale): New procedure.
  (%standard-phases): Add it.
* guix/build-system/gnu.scm (gnu-build): Add #:locale and pass it to
  the build script.
  (gnu-cross-build): Likewise.

build-system/gnu: Add support for zip archives.

Fixes <http://bugs.gnu.org/19866>.
Reported by Andreas Enge <andreas@enge.fr>.

* guix/build/gnu-build-system.scm (unpack): Use 'unzip' when SOURCE ends
  in '.zip'.

Merge branch 'core-updates'

Conflicts:
	gnu/packages/bootstrap.scm

build-system/gnu: Patch /usr/bin/file in all 'configure' files.

* guix/build/utils.scm (patch-/usr/bin/file): New procedure.
* guix/build/gnu-build-system.scm (patch-usr-bin-file): Rewrite using
  it.  Patch all the files returned by 'find-files' that are executable.
* gnu/packages/gawk.scm (gawk)[arguments]: Remove use of 'substitute*'
  for 'extension/configure'.

build-system/gnu: Use executables from the target inputs in 'patch-shebangs'.

Fixes <http://bugs.gnu.org/18895>.

* guix/build/gnu-build-system.scm (patch-shebangs): Add #:inputs
  parameter.  Remove 'bindirs'.  Add 'bin-directories',
  'output-bindirs', and 'input-bindirs'.  Use them instead of (getenv
  "PATH") to as the argument to 'patch-shebang'.

gnu: Revert use of '--strip-all'.

This reverts commits f05bdc9412135f34a1c417edc203c35cd005d0d5
and 856ae5e6c71a1283a414d33e638051f95d3cce35.

This broke all sorts of things.  See <http://hydra.gnu.org/eval/102058>,
for example.

gnu: Don't use --strip-all in cases where this is problematic.

This is a followup to 856ae5e.  See <http://hydra.gnu.org/build/180506>
for an example of build failure.

* guix/build/gnu-build-system.scm (strip): Add #:archive-strip-flags
  parameter.  Use it when (ar-file? path).
* guix/build-system/gnu.scm (gnu-build): Add #:archive-strip-flags
  parameter and pass it down.
* gnu/packages/commencement.scm (gcc-boot0)[arguments]: Add
  #:strip-flags.
* gnu/packages/base.scm (glibc)[arguments]: Likewise.

build-support/gnu: Add support for file patterns in search paths.

* guix/build/utils.scm (search-path-as-list): Add #:pattern parameter
  and honor it.
  (set-path-environment-variable): Likewise, and pass it to
  'search-path-as-list'.
* guix/packages.scm (search-path-specification->sexp): Add PATTERN slot.
* guix/build/gnu-build-system.scm (set-paths): Adjust accordingly.

build-system/gnu: Strip with '--strip-all' instead of '--strip-debug'.

This saves 19% on the 'bin' directory of Coreutils, and certainly
helpful for things like Git's 'libexec' directory.

* guix/build-system/gnu.scm (gnu-build): Change default value for
  #:strip-flags to '("--strip-all").
* guix/build/gnu-build-system.scm (strip): Ditto.
* gnu/packages/linux.scm (linux-libre)[arguments]: Add #:strip-flags.

build-system/gnu: Add support for non-directory search paths.

Partly fixes <http://bugs.gnu.org/18033>.

* guix/build/utils.scm (search-path-as-list): Rename 'sub-directories'
  parameter to 'files'.  Add #:type parameter and honor it.
  (set-path-environment-variable): Likewise.  Pass #:type to
  'search-path-as-list'.
* guix/packages.scm (search-path-specification->sexp): Add 'directory as
  the last item of the tuple.
* guix/build/gnu-build-system.scm (set-paths): Add 'type' to search-path
  pattern.  Pass #:type to 'set-path-environment-variable'.

build-system/gnu: Add 'compress-documentation' phase.

* guix/build/gnu-build-system.scm (compress-documentation): New
  procedure.
  (%standard-phases): Add it.
