For reference:

https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-fs/udev/udev-233.ebuild?id=2f9f0fbb62866409b8ae0252a2b280d148dd9d73

It's pretty ugly. We build around a dozen targets, and (ab)use
automake install targets to selectively install bits and pieces. See
the multilib_src_compile and multilib_src_install functions.

Here's the meson version, for comparison. It's still pretty ugly, and
we have to install things manually since there are no partial install
targets.

Anyway, if you have any questions, feel free to ping me (floppym) on Freenode.
