I have done a little testing on Linux/amd64.

Here i compile lang/gcc7 and the gfortran is able to compile
math/coinmp, so in theory should be working.

But i was again unable to compile math/blas or wip/blas, this time
with a different error (which is of no particular importance to me, my
sparc64 error is the one i need solved):

-- The C compiler identification is GNU 9.2.1
