FWIW I tried to reproduce this and couldn't, even with the same USE flags (manually enabling fma3 on a system without it doesn't seem to hurt anything).
It emerged here at the new tinderbox at few images - so I'd close this bug b/c the old hardware and their images are gone.

Ok, I've found the problem at least. The FC_FUNC macro and its underscore counterpart are supposed to name-mangle C functions to be linked with fortran. But in this case, it can't figure out how to do that: configure:8421: WARNING: unknown Fortran name-mangling scheme So, nothing gets defined in config.h, and the macro winds up "void".
Ah, it's because we're using eautoreconf, and the fortran name-mangling doesn't seem to work the same in autoconf-2.71.

In this -r1, I've added a patch that solves bug 775215 by not setting CC=$CXX during ./configure. At the same time, I've refactored our other build system patch into a series of smaller patches (with explanatory commit messages) that can be sent upstream. Finally, I've removed USE=static-libs support from the ebuild. It doesn't do anyone any good.
