I tracked this down today and just committed the fix as r300438.  The
problem was that MACHINE_CPUARCH was being set to 'armhf' instead of
'arm' because the translation for 'hf' suffix was removed from
share/sys.mk.  We'll need to leave that translation in place for a few
months until everyone running self-hosted armv6hf systems have had a
chance to update.

So now the build with TARGET_ARCH=armv6 should work.  There is probably
some subset of what's in obj/ that could be deleted to avoid a full
rebuild, but I don't know what it is for sure, I just deleted
everything and started over.  My build is not done yet, but it has
gotten further than it did last night, so this fix is looking good so
far.
