Using "make toolchain TARGET_ARCH=arm" gives the same error code.

Tracing down the issue:

/usr/include/machine/endian.h

#define __byte_swap_int_var(x) \
__extension__ ({ register __uint32_t __X = (x); \
   __asm ("bswap %0" : "+r" (__X)); \
   __X; })

r0 looks like an ARM register passed to a non-arm assembler. I'm going to try:

"make toolchains"

And see how that works out.
