Consider the following trivial test program:
int
main (void)
{
gethostbyname();
}
Compiling and linking it with gcc 4.3.0 20070618 configured with gas and gld
2.17
fails:

Adding -rpath-link /lib works around this, but given that /lib is a standard
SEARCH_DIR, this seems wrong. I found that adding -m elf_i386_ldso works, too.
Even GCC 4.3.0 still passes -m elf_i386 by default, so the fact that only
the elf_i386_ldso emulation supports SEARCH_DIRS other than $prefix/...
seems a bug.
