I mostly stole them from newer versions of GCC :-)
the failures for newer FSF GCC (what pkgsrc has) seems to be libgcc
getting misconfigured.

I did see something interesting in the gcc7.1 linux--powerpc libgcc
configure script, where it'd pick float choice based on existing
compiler float options.

on powerpc and ARM, I get something like this:
configure:3686: /usr/pkgsrc/lang/gcc48/work/build/./gcc/xgcc -B/usr/pkgsrc/lang/gcc48/work/build/./gcc/ -B/usr/pkg/gcc48/powerpc--netbsd/bin/ -B/usr/pkg/gcc48/powerpc--netbsd/lib/ -isystem /usr/pkg/gcc48/powerpc--netbsd/include -isystem /usr/pkg/gcc48/powerpc--netbsd/sys-include  -msoft-float -fPIC -mstrict-align -g -O2 -I/usr/include -I/usr/pkg/include -pthread  -Wl,-R/usr/pkg/lib conftest.c  >&5

..

on GCC 7.1 and mips64 I get:
(this one looks like it might be some command line tool differences,
gsed vs. nbsed?)
