i haven't been able to get an i686 or x86_64 build of newlib working at all.
like, not even before i landed any commits.  so it's been hard for me to test
those targets specifically.  cygwin in particular doesn't work out of the box
as building gcc blows up :(.

i sent you a small patch series which should fix this though.

you prob want to run --disable-silent-rules in your CI system so the full
compile commands are logged.
