[bug#43679] [PATCH 1/5] gnu: gcc-toolchain: Add 'GUIX_LOCPATH' to the search paths.

["Ludovic Courtès" <ludo@gnu.org>]

This allows 'gcc-toolchain' to be used as a drop-in replacement for the
default tool chain through '--with-toolchain=gcc-toolchain'.

* gnu/packages/commencement.scm (make-gcc-toolchain)[native-search-paths]
[search-paths]: Append LIBC's search paths.
