4.2/4.3 PATCH: Fix libgomp link tests on IRIX 6 (PR libgomp/32538)

As described in the PR, all libgomp link tests fail on IRIX 6 since
copysignl is undefined.  The following patch fixes this, with the
unfortunate side effect that every program is linked with libm now.

I haven't yet applied this since I don't know yet why only IRIX seems to be
affected: both alpha-dec-osf* and *-*-solaris* have no references to
copysignl in their libgcc.  Is this still the right approach or am I just
papering over an underlying problem?
