Because build-time dependencies are expressed as source packages, not
binary packages.  If you add them to mesa-dri then you'll have to
follow it up with a patch for every recipe that builds more than just
${PN}.

I don't see any reason to bother with that at the moment - we'll soon
have mesa 9.0.2 in oe-core so there won't be any problem.

mesa-dri needs wayland headers for the wayland backend to build, but
there isn't anything pulling in wayland if you enable the distro
feature.

All you need is:

+PACKAGECONFIG ??= "...
+                   ${@base_contains('DISTRO_FEATURES', 'wayland',
'wayland', '', d)} \
+                  "
+
+PACKAGECONFIG[wayland] = ",,wayland"
