svn commit: r248856 - head/share/mk

[Andrew Turner]

As of this commit clang is the default compiler on little-endian ARM.
Can people test this and report back any issues they find. I would like
to keep it as the compiler for when 10 is released.

This doesn't affect big-endian ARM as it is not yet supported by
llvm/clang.
