# Since we don't build gcc and binutils at the same time, gcc's Makefile will try to transform
# program names as gcc's name (add -${version} with ${version} being the version of gcc).
# But it won't work because binutils binaries don't have the ${version} suffix, and even if they
# had, they would actually have the binutils' version suffix (and not gcc's version).
# So let's tell gcc's Makefile not to do that mistake.
