This broke my unified-build-tree bootstrap this week. The default
linker script used by gcc, for emulation elf_i386, no longer searches
for libraries in /lib or /usr/lib after this change. This change in
GCC fixed the problem, but I'm not sure it's the way to go. Is it?
Ok to install?

* config/i386/freebsd.h (LINK_SPEC): Use elf_i386_fbsd as default
linker emulation.
