mhw pushed a commit to branch core-updates
in repository guix.

commit 76e639a00fecb194e2fefc267e2e97c5845434b2
Author: Mark H Weaver <address@hidden>
Date:   Wed Jan 7 15:00:44 2015 +0000

    gnu: gcc: Use 'gcc-configure-flags-for-triplet' for native compilers too.
    * gnu/packages/gcc.scm (gcc-configure-flags-for-triplet): Do not export it.
      (gcc-4.7): Pass the result of 'gcc-configure-flags-for-triplet' to 
      for all builds, including native ones.
    * gnu/packages/cross-base.scm (cross-gcc-arguments): Do not add the result 
      'gcc-configure-flags-for-triplet' here, since it is now included in the
      configure-flags inherited from gcc-4.8.
