If you use gcc 4.2.2 to buildworld, it does a two stage build. It starts
by building the base gcc (4.2.1) withe the default compiler and then
builds it again using the just built compiler. You should be fine if you
define CC as gcc422. It will only be used to build the gcc4.2.1
compiler. Once that is done, the make system will use only the newly
If you have removed /usr/obj/*, you can speed the build with -DNO_CLEAN.
(There is nothing to clean, but make will still try.) Since there is
nothing to clean, making cleandir and cleanworld looks unnecessary,
Unless you have a 6 core system, -j7 is probably excessive. Both my own
tests and those of others show that having one more build thread than
there are processors seems to be the sweet spot. (I don't recall if
anyone has tested at over 6 cores, though.)
I think I understand the build system, but I am far from a make(1) guru,
so. if I misunderstand any of it, hopefully those who are will chime in
with the right information.
