[LTP] problems building lchown02.c for uClinux

[David Marlin <dmarlin@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 263 bytes --]


'lchown02.c' does not build properly due to calls to mmap and
get_high_address (which references sbrk) when UCLINUX=1 is defined.

Attached is a patch to skip those sections of the test when building for
uClinux.
