Yes, CONFIG_LINUX_USER will always be defined in linux-user/elfload.c,
while CONFIG_BSD_USER will always be defined in bsd-user/elfload.c. The
same way using CONFIG_BSD in linux-user/elfload.c doesn't make sense,
as this code will never been compiled.

That's sound strange, if you do that I think you will need to use the
bsd-user code, not the linux-user code.

I have to say I don't really understand the reason why this BSD code is
there.
