Has anyone really looked into the feasibility of adding distcc support to the
ports system? I realize that not all ports support concurrent make, but
those that do could potentially take advantage of it. What I propose is a
flag in the port Makefile, SUPPORTS_MAKE_CONCURRENCY. Then users could add
WITH_MAKE_CONCURRENCY to make.conf to build ports that support it with make
concurrency. Then an additional WITH_DISTCC flag in make.conf to use distcc
when making with concurrency.
I made a minor change to bsd.ports.mk to do this and it seems to work pretty
well. Here is my patch to bsd.ports.mk. What do you guys think?
