A recent change added a use of xe_wa_oob.h without adding the file that
uses it to uses_generated_oob, which means xe_wa_oob.h does not get

After adding '$(obj)/xe_guc_ads.o' to uses_generated_oob, xe_wa_oob.h is
always generated before building the file, resulting in no errors:

We probably need to find a way to make sure we generate it before
anything else. Maybe it'd be simpler to just do this:

Apparently works for me:
