Unknown symbol EVFILT_USER for bee.epoll on OpenBSD

[lcheylus]

I'm trying to compile latest version of luamake on OpenBSD current/amd64.

I have an error during build with unknown symbol EVFILT_USER.

$ cd luamake
$ ./compile/build.sh

After a few analysis, this error is due to the recent addition of bee.poll (source bee/net/bpoll_osx.cpp): the symbol EVFILT_USER is not supported on OpenBSD => see include sys/event.h https://github.com/openbsd/src/blob/master/sys/sys/event.h

Before the recent addition of bee.poll, I have no issue to compile luamake on OpenBSD amd64.

I have removed EVFILT_USER.

OK, thanks.

With update of bee.lua submodule, my compilation of luamake on OpenBSD/amd64 is OK.
