Is this really worthy of generating a warning?  In general, isn't the
last option given supposed to 'win'?

I'd think that it might ... cause lots of unnecessary warnings if
e.g. there were a way to set the built-in default configuration (i've
not looked how that's done in the new code), or if somebody did e.g.:

	AS="mips-elf-as -march=r4000"

then later explicitly coded things in their makefiles as:

	$(AS) -march=...
