Define __wrap_exit in test program source for XORG_LD_WRAP
Otherwise the test fails on Solaris releases that actually have support for ld -wrap because the linker instead returns an error that __wrap_exit is an undefined symbol. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Jeremy Huddleston <jeremyhu@apple.com>
