There was a hack somewhere in joyent/libuv to make it work on OSX, but
IIRC this was a problem with GYP on OSX, it does work on Linux.

I submitted https://github.com/libuv/libuv/pull/285 to fix these warnings.

A quick search shows that pthread_sigmask might not be supported
proberly on Andoird. We might need to skip the test there.

work. Have you tried using the resulting library from the autoconf
build? Any problems there?
