The only thing that can keep track of where we started vs. where we cd to
is the shell, and so we'd have to trust what it says PWD is.
A possible pseudo-solution would be to give our *build system* (note:
NOT the make program) a .TOPDIR variable which would be intiailised to
something sane to begin with, and build relative/logical paths on top
of it, i.e.
.TOPDIR + realpath(".") - (realpath(.TOPDIR) - .TOPDIR)
To get the current directory.
But damn that's messy, damn that's a lot of overhead, and I think at that
point we're really stretching how much can be gained from such things.
