 >Release:	NetBSD-HEAD
 >Environment:	NetBSD 8.0_BETA macppc powerpc
 >Description:
 Attached test exercises the bug in kLua reported as port-macppc/52864.
 I have not been able to perform a full build test due to the lack of resources so It is possible I may have a step with file set lists??
 
 Should the category for this PR be switched to the kern category as the issue was not just port-macppc specific?
