description:
Re-add direct symlink logic, optional under GCC_USE_SYMLINKS=yes.  Saves
one fork/exec step on platforms where gcc is compiled with hardcoded gcc-lib
pathnames.  This applies to most platforms, but the default currently
remains not to use symlinks so as to avoid unexpected gotchas for users.
