gnu: gcc: Always link against libgcc_s.so.

* gnu/packages/gcc.scm (gcc-4.7)[pre-configure]: Add snippet to #undef
  USE_LD_AS_NEEDED.

gnu: tar: Upgrade to 1.27.1.

* gnu/packages/base.scm (tar): Upgrade to 1.27.1.

* gnu/packages/base.scm (glibc): Add 'snippet' to set use_ldconfig=no.
  Remove "glibc-no-ld-so-cache.patch"; that patch would still build
  'ldconfig', and ld.so would still contain ld.so.cache-related code,
  and would look for info in /etc/etc/ld.so.cache (sic).
* gnu/packages/patches/glibc-no-ld-so-cache.patch: Remove.
* gnu-system.am (dist_patch_DATA): Adjust accordingly.

gnu: Switch to GCC 4.8 as the default compiler.

* build-aux/download.scm (file-name->uri): Update URL to /20131110.

  nodist_bootstrap_i686_linux_DATA): Change base name to
  'guile-2.0.9.tar.xz'.

  (gnu/packages/bootstrap/mips64el-linux/guile-2.0.9.tar.xz): Update
  hash.
* gnu/packages/base.scm (gcc-boot0): Base upon GCC-4.8.  Enable C++, and
  add a few --disable flags.  Remove MPFR workaround.
  (cross-gcc-wrapper): Base upon GCC-4.8.  Wrap both 'gcc' and 'g++'.
  (libstdc++): New variable.
  (gcc-final): Add it as an input; pass corresponding -I and -L flags.
* gnu/packages/bootstrap.scm (%bootstrap-guile): Always use
  "guile-2.0.9.tar.xz.
  (%bootstrap-coreutils&co): Update hashes.
  (%bootstrap-binutils): Update URL and hashes.
  (%bootstrap-glibc): Likewise.
  (%bootstrap-gcc): Likewise.
* gnu/packages/gcc.scm (gcc-4.7): Add LDFLAGS.
  Add --disable-libstdcxx-pch.
  Modify the GNU_USER*_SPEC macros from gnu-user*.h instead of the raw
  _SPEC macros.
