[PATCH 2/3] feature-arm-thumb.inc: drop legacy _thumb and _thumb-interwork over-rides

[Andre McCurdy <armccurdy@gmail.com>]

Bitbake over-rides for _thumb and _thumb-interwork are undocumented
and are not used anywhere in oe-core or meta-oe. The logic setting up
the thumb-interwork over-ride even seems to be reversed and nobody
noticed, so it seems safe to assume that these over-rides are not
used.
