Applied, thanks. It fixes build issues like
http://autobuild.buildroot.net/results/022b73a989734d800225c91f419f18f4fc31c264/build-end.log.

Danomi, could you share what is your Buildroot configuration that uses
-mfpu=neon -mfloat-abi=softfp ? I might be interested in adding such a
configuration to the autobuilders.

Thanks!

Thomas
