Subject: [PATCH] c6x: asm: Add default flat.h according to xtensa architecture

For supporting uClinux flat-format executables, c6x needs to define the fewest features to support it, at present, xtensa architecture has the fewest feature for it, so just copy xtensa flat.h. The related error:

CC fs/binfmt_flat.o

Thanks! I added this to the c6x tree for next merge window.
