gnu: gcc: Add a "lib" output.
* gnu/packages/gcc.scm (gcc-4.7)[configure-flags]: Add --with-gxx-include-dir. [outputs]: New field. [arguments] <phases>: Adjust to use the "lib" output. Add 'substitute*' calls for "libstdc++-v3/python/Makefile.in" and "gcc/config.in". * gnu/packages/base.scm (gcc-boot0) <symlink-libgcc_eh>: Use the "lib" output. (cross-gcc-wrapper): Add 'outputs' field. (glibc-final)[arguments]: Adjust #:allowed-references to list '(GCC-BOOT0 "lib"). (libstdc++): Add 'outputs' field. (gcc-final)[arguments]: Add "lib" to #:allowed-references. * gnu/packages/make-bootstrap.scm (%gcc-static): Add 'outputs' field.
