I would recommend setting PKG_CONFIG_PATH/PKG_CONFIG_LIBDIR which should make
the above CPPFLAGS obsolete. Your choice of CPPFLAGS is very hacky imho.

Also as Tapani mentioned CPPFLAGS="${CXXLAGS}... may not be the best of ideas.

AFAIK as one provides a new sysconfdir, the value is independent of
PREFIX/EPREFIX. Thus setting it to /etc while the latter two are ${XBUILD} is
not something I've seen and/or encourage.

Guilty, I've never used the script as mesa's build has changed substantially
since it originated. I use a simple 10-liner script that sets the options that
I need from mesa.

Please set PKG_CONFIG_... as suggested above and drop the CPPFLAGS altogether.
Mesa's build has always been less than stellar, and allowed people to exploit
it to the limits. Recent changes have made things a bit saner.
