If no explicit --enable-thumb or --disable-thumb is given configure uses the
thumb
if the compiler defines the symbol __thumb__. Apples toolchainin Xcode5 does
that.

Using thumb2 (that's what --enable-thumb makes) shouldn't make a big
difference.

There were a couple of problems related to gas-preprocessor and thumb but those
should be fixed since january.
