* Compiling against musl correctly points out that including sys/poll.h is
* disallowed by the Single UNIX Specification when building in userspace. We
* implement a dummy header to redirect the include to the proper header.
* However, glibc, klibc and uclibc break this shim by including sys/poll.h
* from poll.h, so we add explicit exceptions for them.
