Well, _I_ would do it like this:
find -name 'Makefile' |xargs -i sh -c "sed 's/-Werror//g' {} |safe {}"
You can find safe here:
http://www.ibiblio.org/pub/Linux/utils/text/safe-2.0.9.1.tar.gz
if 2.0.9.1 isn't there yet, 2.0.9 will do, I only changed my email
address in the doco.
This also seems to work:
find -name 'Makefile'|xargs -i perl -pi -e 's/-Werror//g' {}
