Hi Bamvor,

This patch works as intended for tests that use the default
INSTALL_RULE. In the cases where INSTALL_RULE is overridden
as in the case of powerpc, powerpc directory still gets created
during install.

It would be nice if we can fix it for the override cases as well.
I will get this into 4.3 for now. Would you like to send a patch
to fix the override cases as well??

thanks,
