You need to narrow your thinking to GCC and binutils the processes of
consequence. You only need to specify the triplet because config.guess
guesses wrong based on the value of `uname -s'. The cygwin binutils as

CYGWIN1.DLL without having to do anything special with their names or
output. So, my statement stands based on what happens with GCC, you're
switching the build environment.

No, you're not doing a cross build, therefore I've stated the correct
