Fix configuration on Solaris 8.

There is an quoting error in Gnulib's threadlib.m4 which causes
incorrect configuration settings on old Solaris.  We can repeat
the simple check with correct quoting to workaround the problem.

Additionally, pull in DX_LINGUAS fixes from dxcommon to avoid
tripping on Solaris' pre-POSIX /bin/awk.
