The following removes adding -lieee to the link command when -mieee-fp
is specified for GNU targets as suggested by Joseph in the PR.  It doesn't
touch m32r so the fix may be incomplete depending on the C library used.

I've added a testcase that makes sure we can link but not functional
tests of -mieee-fp which I suppose exist already (eh...).

Bootstrap and regtest is running on x86_64-unknown-linux-gnu with
glibc 2.27 where the testcase fails before the patch.

OK for trunk and active branches?

Thanks,
Richard.
