PATCH (ld/testsuite, binutils 2.14): i386-unknown-freebsd4.8 tweak

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

Testing gcc 2.95.X (as installed as system compiler) to FSF mainline
against binutils ~2.14 on {i386,alpha}-unknown-freebsd4.8 reveals that
this xfail hasn't been required for some time and that this new logic
to conditionally find ld-elf.so.1 is more robust (since it will take
the file produced if actually found; I rewrote a patch I've had in my
tree for ages; gcc on FreeBSD keeps this special library outside any
place that would typically be searched thus defeating gcc's generic
library-finding logic).  With this test suite patch, no failures on
i386-unknown-freebsd4.8.

	* ld-undefined/undefined.exp (i?86-*-freebsd*): Remove xfail.
	* ld/configure.host (*-*-freebsd*): Add known path for ld-elf.so.1
	if not produced by gcc.
