I thought that in general we wouldn't know what the default endianness of the 
assembler we are targeting is so it was safest to be explicit. For a 
cross-toolchain it is probably inherent in the name, but in theory we could be 
running clang on a native big-endian system where the assembler is just called 
as.

Ok will add some more tests.
