ok, this turns out to be a simple issue. The gas for arm is not
found since CROSS_COMPILE has a trailing dash. When it is removed
the correct as is picked up (and libs is found automagically as well).
Both the 3.4 and 3.5 binary packages from Ubuntu are able to
compile u-boot with this change, so the README should be updated.

This should work:
make HOSTCC=clang CC="clang -target arm-linux-gnueabi -mllvm 
-arm-use-movt=0 -no-integrated-as" V=1 all
