you'll need to clarify.  it builds fine for me, it just may not run
correctly due to the assumptions of memory placement.

for runtime issues, how about we change lib/get_high_address.c to
return NULL for UCLINUX targets.  then in lchown.c, we can check for
NULL and skip the test when we get that value.

that leaves your ifdefing of -1 pointer address.  any sane nommu port
should reject that address in the kernel.  if yours isnt, fix your
kernel.
