[Patch, libgomp, testsuite] Another libquadmath tweak.


If the target embeds the dependency of libgfortan -> libquadmath, then uninstalled testing of libgomp.fortran can fail because the path to libquadmath is unknown in the libgomp test harness.

Note that libgomp uses xgcc to drive fortran tests - not gfortran (so we have to supply needed libs by hand).

As discussed with Tobias and Dominique on irc.

tested with uninstalled make check-target-libgomp on {i686,powerpc}- darwin9.
OK for trunk?


	* testsuite/libgomp.fortran/fortran.exp: Add paths for libquadmath.
