Committed: fix ld/configure.tgt for mips*-freebsd*

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

An obvious typo, correction committed as such.  It's obvious
when looking at configure mips*-freebsd* checks in other
binutils directories and observing that FreeBSD GNU triplets
(not referring to the kFreeBSD thingy) look like
<arch>-freebsd<releasemajor>.<releaseminor>.  It seemed only the
mips* entries had this typo.

This change apparently lacked sufficient testing.  A suitable
penance would be testing recent binutils and GCC releases and
submitting results for inclusion in the
<http://gcc.gnu.org/buildstat.html> pages, for any *-freebsd*
(sic; not kfreebsd) and GCC releases missing recorded results (I
looked there to get the gist of the general status of FreeBSD
support).

It's also obvious binutils could use some MIPS FreeBSD T.L.C.:
CVS HEAD cannot have been built since 2010-12-31 when the
breaking patch was committed.

Tested by building crosses for mips-freebsd8.2,
mips64el-freebsd7.3, mips64-freebsd8.1, mipsel-freebsd7.2
(canonical names: s/-freebsd/-unknown-freebsd/) which fails in
ld without this patch, as follows:
...
checking whether ANSI C string concatenation works... yes
*** ld does not support target mips-unknown-freebsd8.2
*** see ld/configure.tgt for supported targets
make[2]: *** [configure-ld] Error 1

Another FreeBSD-related wart, noticed while testing the fix for
the issues I really had in mind (this being a side-track for
issues with testresults for other MIPS targets), is that
binutils/testsuite/lib/binutils-common.exp:is_elf_format returns
0 for *-freebsd* targets, while is_aout_format returns 1 only
for freebsd[12].  That also seems just wrong, but I leave that
for people actually interested in FreeBSD.

ld:
	* configure.tgt (mips64*el-*-freebsd*, mips64*-*-freebsd*)
	(mips*el-*-freebsd*, mips*-*-freebsd*): Correct triplets by
	replacing trailing "-*" with "*".
