Hmmm...
Actually, I'm thinkg that src2obj() should check if the original file exists as
given before changing .S to .s... That should work, since we're always
generating 'foo.s' from 'asm/foo.S' (or 'asm/foo.pl', but that's not applicable
here)... The directory difference should make it safe.
I'll experiment a little, there's also the question of the assembler files in
crypto/, but they are a problem in other builds as well...
So, fix coming up! But not quite your solution.
