Simple patch

It leaves -plugin-opt in LINK_COMMAND_SPEC, but I think it is not quite right,
as LIBGCC_SPEC and LIB_SPEC are redefined by many targets (and, for example,
choose libc or libc_p depending on -p / -pg / -profile).

GCC r155915 bootstrapped with this patch on i686-pc-linux-gnu with and without
--disable-shared option. It seems to work.
