Ah, you'll probably have to re-run configure and rebuild the cross compiler.
The configure/build process checks for the presence of the cross-assembler
and decides which one to use.

Hmm, it seems configure does use a couple of fallbacks to determine
byte order if sys/param.h doesn't exist, but those require a working
cross-assembler ...

Generally speaking, the configure process should work on non-POSIX
systems that don't provide those headers. But it may well be that
something is broken in this case; this will be rarely tested ...

See above; you should try to rebuild the cross-compiler first.

For now, just patching configure to see how far you get is of course fine.
Longer term, however, note that configure is a generated file. You'd have
to make those changes either in configure.ac or possible within the
autoconf machinery that generates the file.
Bye,
