[OE-core] [oe-core][PATCH 1/1] qemumips64: no qemu-usermode for n32

[Slater, Joseph]

I think values for the BACKFILL_CONSIDERED can be used, but only if they are literals.  I don't think any variable expansion occurs when getVar() is used at the point of backfilling.  I think the a better way of setting MACHINE or DISTRO_FEATURES would be to directly append/remove  using overrides.  In any case, I do not believe any of the CONSIDERED definitions work.

features_backfill() is called from meta/classes/base.bbclass ->
base_eventhandler() in response to bb.event.ConfigParsed (ie "when the base configuration; which consists of bitbake.conf, base.bbclass and any global INHERIT statements; has been parsed") so anything assigned to DISTRO_FEATURES_BACKFILL_CONSIDERED or MACHINE_FEATURES_BACKFILL_CONSIDERED after that event won't be seen...
