Since VAR_append can appear multiple times,
bbappend files can equally do

GALLIUMDRIVERS_append_x86_class-target = ",iris"
GALLIUMDRIVERS_append_x86-64_class-target = ",iris"

instead of this PACKAGECONFIG.

Anyway, since this MR exists in Mesa:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8015
after a certain point this will have to be used in the
upstream recipe (pseudo-patch follows):

...
-DRIDRIVERS_append_x86_class-target = ",r100,r200,nouveau,i965,i915"
-DRIDRIVERS_append_x86-64_class-target = ",r100,r200,nouveau,i965,i915"
...
+GALLIUMDRIVERS_append_x86_class-target = ",nouveau,i915,iris"
+GALLIUMDRIVERS_append_x86-64_class-target = ",nouveau,i915,iris"
...
