Add experimental support for -j jobs building in the build
target.
MAKE_JOBS is undefined by default. You can test this by setting
in mk.conf: MAKE_JOBS=5 for example.
Some package just won't build correctly with this -- these individual
packages can set MAKE_JOBS_SAFE=no to disable it.
This is based on discussion from last December 2005. Some pkgsrc
users are using ideas like this.
Note I have been using this since December 2005 on various single
processor and multiprocessor systems. (Once I kept some stats on
performance but have misplaced that now.) I haved tested this with
many packages (but not a bulk build) on Linux, NetBSD and DragonFly.
This commit doesn't include the commits for the MAKE_JOB_SAFE. As
this is experimental it needs more testing. Some examples of problems
are: comms/lrzsz, databases/gramps2, editors/vim, graphics/MesaLib,
graphics/netpbm, net/bind9, print/ghostscript-esp, textproc/libxml,
and www/lynx.
