gcc.c (LIBGCC_SPEC): If REAL_LIBGCC_SPEC is defined...
* gcc.c (LIBGCC_SPEC): If REAL_LIBGCC_SPEC is defined, and
LIBGCC_SPEC isn't, set LIBGCC_SPEC to REAL_LIBGCC_SPEC.
(init_gcc_spec): Don't define or call if REAL_LIBGCC_SPEC is
defined. Instead use REAL_LIBGCC_SPEC, unmodifed, as the libgcc
spec string.
* doc/tm.texi (REAL_LIBGCC_SPEC): Document.
