gcc doesn't install iso_c_binding.mod, and the pcmsolver project
(https://github.com/PCMSolver/pcmsolver) fails:

> F90-F-0004-Unable to open MODULE file iso_c_binding.mod 
> (/wrkdirs/usr/ports/science/pcmsolver/work/pcmsolver-1.2.1/src/metal/metal_sphere.F90:

> F90/x86-64 FreeBSD Flang - 1.5 2017-05-01: compilation aborted

Googling iso_c_binding.mod finds some more instances of a similar problem.
