LTP test cases kill05 is broken on uclinux platform.
--
root:/bin> kill05
kill05 1 BROK : self_exec of child failed
kill05 0 INFO : WARNING: shared memory deletion failed.
kill05 0 INFO : This could lead to IPC resource problems.
kill05 0 INFO : id = 0
kill05 2 PASS : errno set to 1 : Operation not permitted, as
expected
kill05 0 WARN : tst_rmdir(): rmobj(/tmp/kilhsxPSp) failed:
lstat(/tmp/kilhsxPSp) failed; errno=2: No such file or directory
root:/bin>

Bellow is the fix for uclinux platform. And the permission of kill05 should
be set to be executable by every user.
