As described in the PR, the fact that the libgomp testsuite always links
with -lgomp, even with -fno-openmp, causes testsuite failures on targets
(like Solaris) that need special options when linking libgomp. With
-fgomp, this is taken care of by the relevant specs (like adding
-pthread), but not so otherwise.
I found no reason for that explicit -lgomp since this is already dealt
with by -fopenmp.
The following patch fixes the failures on Solaris 8 and was tested with
make check in libgomp on sparc-sun-solaris2.8, i386-pc-solaris2.10, and
x86_64-unknown-linux-gnu.
Ok for mainline and 4.6 branch?
