libwayland-egl.so missing 'wl_drm_interface'

[Matt Hoosier]

I had done all that, but was still getting the error. Finally I tracked it
down to what appears to be an internal Makefile problem in Mesa's
libwayland-egl directory. libwayland-drm.a provides this symbol, but wasn't
getting linked into the overall libwayland-egl.so binary. See the attached
proposed patch.
