The binary size for 32-bit targets is still reasonable with this
addition (thanks to Thumb2).

But if I enable MUSB for the Pine64 it generates a 537KB u-boot.itb. And
the build process does not complain, I guess because I don't generate a
combined binary (glueing SPL in front). But this isn't really caused by
this patch, so just a heads up.

Cheers,
Andre.
