Ok. Just in case, I'll run a check on whether crt0.S can be assembled
for Thumb and still wrk as expected. :)

Do you have a list of source files which still build for ARM under
CONFIG_SYS_THUMB_BUILD? I' would prefer all of the code to be thumb for
consistence, except probably... exception :) entry points -- and even
these should be able to run in full Thumb 2.
