Thanks. Unfortunately that still doesn't answer the
question. It says:

Still '-march=pentium-m' (which is available for gcc)
is not recognized by clang. So I am afraid I don't
know how to use this info practically.

I have also seen:

https://clang.llvm.org/docs/CrossCompilation.html#general-cross-compilation-options-in-clang

but it is still not clear what hides behind those
"etc". It doesn't even mention -march and there no
clear list of what one can use for -mcpu. This is
very confusing.
