>Description:
the patch includes /usr/obj/lib32 in the cleanworld target. the patch only scrubs the directory if it's present (which means cleanworld on anything != amd64 won't change). the patch also honours envar MAKEOBJDIRPREFIX.

this was discussed in [1].

cheers.

>How-To-Repeat:
`cd /usr/src && make cleanworld`

=> /usr/obj/usr/src gets scrubbed, but /usr/obj/lib32/usr/src doesn't.
