Indeed.

Hmm ...configure should error out if the these two deps. are unmet. We
either have a bug or there's some extra patches somewhere ;-)
Can we have .pc files for the extra libraries (something like below,
with the @@ expanded). That way one can use
PKG_CHECK_MODULES(ANDROID_EGL, ....) PKG_CHECK_MODULES(ANDROID_DRI,
...) and the respective _CFLAGS, _LIBS in the targets.
prefix=@prefix@
exec_prefix=${prefix}
libdir=@libdir@
includedir=@includedir@
Name: xatracker
Description: Xorg Gallium3D acceleration library
Version: @XA_VERSION@
Libs: -L${libdir} -lxatracker

Indeed it does. I'll push these two in a second, but please follow up
with any extra patches to make things a bit easier to manage.
