distutils: gnu: patch fcompile

This allows mingw's gfortran to work with MSVC. DLLs are
autogenerated using heuristics that should work with most
cases. In addition, a libopenblas DLL is compiled from
the static lib for use with MSVC.

All generated DLLs have randomized names so that no clashes
will occur.
