[PATCH v3 0/3] Add math support for non LDBL_EQ_DBL architecture

Thanks.

I have pushed it to sourceware.org. Jennifer has confirmed it matches her
expectations.

I have updated the hash in the RTEMS Source Builder and am building tools
now. Once I push that patch, our CIT should build on about a half dozen
hosts. RTEMS uses about 18 architectures so that should be pretty good
coverage.

Hopefully that all comes out ok and no one else spots any anomalies. This
was a large patch set.
