Andre McCurdy c13eb4ff7c feature-arm-thumb.inc: fix ARM_THUMB_SUFFIX for armv8
The current definition for ARM_THUMB_SUFFIX doesn't consider armv8
and will therefore cause TUNE_PKGARCH to be set incorrectly for
machines which inherit arch-armv8 and don't include aarch64 in
TUNE_FEATURES (ie when building for 32bit ARMv8).

Also fix typo in comments and improve TUNEVALID[thumb] wording.

(From OE-Core rev: 3691fd7dbe7f01ca29c14fc603c6946864af3b3c)
