I'm not sure why this is happening; are you sure that -EL is the
right command line option to build a little endian ARM binary?  I'm
not so sure.  You should check the documentation.

This won't work -- you've emitted preprocessed source to hello.x.
hello.x needs to be a valid ELF object file (you can test this with
file(1) when you think you've got it right).
