OK. At this point, on ARM BR2_USE_MMU disabled or BINFMT_FLAT=y is
equivalent. But right, it's a elf2flt related issue, so testing
BINFMT_FLAT makes more sense.

I have no idea if Xtensa noMMU has ever been tested, whether it uses
FLAT or FDPIC, etc. Could we leave this up to people interested in
Xtensa ? Or alternatively, remove noMMU Xtensa support altogether.
I'm Cc'ing Max to see if he knows what the status of noMMU Xtensa is.
Thanks!
