it is certainly possible to build OpenBLAS with clang as C compiler and
gfortran as Fortran compiler.
Not sure how to do this using OpenBLAS port machinery, but

CC=clang FC=egfortran cmake && gmake && gmake test

works for me on 6.7. It seems that clang's llvm assembler is used in such a
configuration.

(I suppose egfortran is installed as a part of g95 package, and provides gfortran 8.3)

Hope this helps.
