build gfortran for osx with other gcc compilers?

[beckermr]

Right now we have separate gfortran builds for osx in different feedstocks. If we are moving to a gcc feedstock, we should probably archive those builds and move them to the gcc feedstock. One thing I don't understand is if we need two builds of gfortran, one meant for the clang stack and the other mean for a gcc stack for osx.

gfortran build for osx are pretty special, because it builds gfortran only and skips C/C++. We don't need two builds of gfortran, but I don't think we should go for a gcc stack for osx. We should stay with one C++ standard library for one platform to keep the CI matrix sane.
