Fixes gfortran compilation failures caused by missing 'break' in the fix for PR22234 committed in r227409.

[tra]

Summary

Due to missing break -fcompile-only was always passed to fortran
compiler which in turn didn't produce any output which caused
assembler to fail.

LGTM, sorry I missed this in review. I'll commit shortly.

Thanks!
