I tried this on ppc64le and it fixes 2 tests, so were at

	Out of 287 tests, 273 passed, 14 failed (10 of them are known to fail)

The repaired tests are:

	backend/hello.c
	backend/sum.c

unexpected failures are:

	backend/arithmetic-ops.c
	backend/cmp-ops.c
	backend/int-cond.c
	backend/logical-ops.c

These are not about missing preprocessor tokens as there are no system
includes used, but the error there is

	Error: unrecognized opcode: `...`

. I didn't look into what the problem is there, but attached the test
log.

I did a build test on a few other Debian machines, arm64 was fine, mips
and mipx64el had 15 failures, ppc64 (i.e. big endian) had 12. I didn't
look in more detail and suggest to tackle one after the other :-)

Best regards
Uwe
