I don't understand what you mean by that, I build

     Make the ti_mbox and ti_pruss drivers optional.

     MFC after:  1 week

with
make XDEV=arm XDEV_ARCH=armv6 xdev
make XDEV=arm XDEV_ARCH=armv6 xdev-links

resulting in

FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512
Target: armv6--freebsd
Thread model: posix

So I am not behind (too much) if that is what you meant.

I don't know the root cause, but clang e.g. will behave differently
depending on the name it is invoked with. So perhaps that logic needs
to be extended then.

No idea, I do know 2 more people reported the same problem in the
u-boot mailinglist before, so it is not limited to my setup. I just didn't
encounter it before, since I typically don't build u-boot as root.
