We already have a check for NO_SENDMAIL in usr.sbin/Makefile - is that
not enough?  Maybe there's a way to extend this so that if you have a
subdir target (say FOO) that is relative to BSDSRCDIR it doesn't get
built if NO_${FOO} or DONT_BUILD_${FOO} (or even NO_${SUBDIR}_${FOO}, eg
NO_USRSBIN_SENDMAIL) is set.  I suspect that the make magic to do this
will probably be ugly...

In the mean time, I guess people don't install releases as often as
people rebuild the world.
