The man page says '`.OBJDIR' may be modified in the makefile as a global
variable.' which is just plain wrong.
I think it can be changed like that, but nothing special happens, so
the effects will be unexpected at best!

I also suspect that build.sh could be changed to that everything
used ${MAKEOBJDIR} eg MAKEOBJDIR=${.CURDIR}/obj.${MACHINE}.${BUILDID}
So that the variations in the makefiles wouldn't be needed.
It ought also be possible to requests that make itself create the
'obj' directory when MAKEOBJDIR or MAKEOBJDIRPREFIX is defined.
