Yes, the 3 procedures can compile C files, but the last 2 pass -c to GCC while 
the first 1 passes -S and then invoke GAS manually.  The rationale for the 
discrepancy is rather unclear to me...

I was rather thinking of making run_ld_link_tests behave like the other 2: if 
you compile a C file, invoked gcc -c , if you assemble a S file, invoke as -c.
