I'm sorry it looks like it was caused by bbappend in one of our layers.

We were using this bbappend with older mesa version and it set PACKAGECONFIG[dri3] to empty, because of unrecognized mesa options in that version.

It looks like non-x11 builds gained X11 dependency and mesa fails to
build in DISTROs without x11 in DISTRO_FEATURES:

mesa-11.1.1/src/loader/loader_dri3_helper.c:28:27: fatal error:
X11/xshmfence.h: No such file or directory

Just had a look at this. The dri3 packageconfig explicitly depends on xshmfence and if disabled then --disable-dri3 is passed. Can you replicate this, and if so can you share the configure log?
