Look into the file <prefix>/lib/openpkg/rpmtool. There is a section
"mflags" where for particular operating systems the number of CPUs is
determined, the make variant is determined, and according to those two
information the flags for a "parallel make" procedure is activated. If
you add a section there for AIX most packages (those using "%{l_mflags
-O}") will build with parallel make procedures. If it works, please
contribute back the section you added.
