Log Message:
libepoll-shim: add builtin.mk to skip on Linux

libepoll-shim is required for systems that have kqueue but not epoll.
Linux does have epoll, so it is (a) unnecessary and (b) doesn't build.

The detection logic is currently hardcoded to Linux only; I suppose it
could be improved further.
