I compile directly on Gentoo Linux on my RPi2, with some assistance via
distcc.

As I said, you need to point it towards the raspberrypi-userland headers
and libraries, because they aren't installed in /usr, but /opt/vc.
Though looks like I was a bit confusing due to rewriting the sentence
and ending up with bad flow.

Basically something like:

LDFLAGS='-L/opt/vc/lib' CPPFLAGS='-I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux'
in environment for the configure call.
I myself patch rpi-userland to provide pkg-config files and patch
gst-plugins-bad to use them, but passing appropriate CPPFLAGS and
LDFLAGS should work.

For WAYLAND_EGL, you would have to patch raspberrypi-userland with
wayland patches that have not been included in there yet.
I think it was just looking for any EGL thing, so once you point
CPPFLAGS at it, it should find them and get further.
