Try harder to use the C compiler for compiling asm

Use an ordered dict for the compiler dictionary and sort it according
to a priority order: fortran, c, c++, etc.

This also ensures that builds are reproducible because it would be
a toss-up whether a C or a C++ compiler would be used based on the
order in which compilers.items() would return items.
