netbsd-8 epoxy woes

[Greg Troxel <gdt%lexort.com@localhost>]

In the land of pkgsrc, we have had trouble with netbsd-8 native epoxy,
specifically in the compilation of xentools411, to which a workaround
was recently committed.

The root of the problem seems to be that epoxy/egl.h tries to include
EGL/eglplatform.h, which does not exist.

I am not clear on epoxy in general, but this seems like a serious bug in
native epoxy that makes it unusable.

(Separately, there is a question of whether pkgsrc should even try to
use netbsd-8 native epoxy via x11-links, but this query is about the
state of epoxy itself.)
