Hello. I would like to enable multilib support for dev-util/google-perftools, because some proprietary x86 program requires it. I've made some work on it here: https://github.com/cdkrot/gentoo-overlay Actually it appears to be working (x86 binaries are compiling too), but i am not sure, may be it requires some modifications to fit in established best-practices. Best regards, Dmitry.
