How does one indicate a system source directory location when in other
than /usr/src?
That could be necessary when in another directory, for instance running
ndiscvt.
Or one could be building FreeBSD for a USB stick and want to do the
heavy work on a hard drive; I could also want to build and install ports
on the USB stick but do the heavy work on the hard drive.
I couldn't find a variable named SRCDIR anywhere in the documentation,
in contrast to PORTSDIR, which I did find.
I may also want to build 10-CURRENT from 9-STABLE system without giving
up the 9-STABLE source tree; I would need both source trees, but then
after the first successful build of 10-CURRENT, I could use that to
build updated versions.
I often use nullfs for this kind of thing:
mount -t nullfs /where/your/sources/are /usr/src
mount -t nullfs /some/dir/for/objects /usr/obj
