I don't think it implies that: why cannot cc_stack_align_opt probe for the 
compiler option and use whichever is available, without hard-coding the compiler 
name?

I concur with hpa: hard-coding compiler is awfully fragile and ugly as well.

With the proper probing of compiler options it will be possible for compilers to 
consolidate their options, and it would be possible for a third compiler to use a 
mixture of GCC and Clang options. With hard-coding none of that flexibility is 
available.

Please do.
