Currently, emul packages can install /usr/lib32/pkgconfig files (when enabling "development" USE flag). This was added because, as emul sets tend to be obsolete in a few weeks, people compiling packages against its lib32 provided libs were getting build failures due "native" pkgconfig files (usually from newer libs) were being used. Regarding /usr/include, it looks harder to solve, current emul packages simply don't provide headers at all, but it caused issues like this in the past: https://bugs.gentoo.org/show_bug.cgi?id=299490 Maybe installing headers in other place would be interesting :/
