The idea behind this is that intermediate results can be put anywhere,
you don't need to know where.  Since $BDIR differs from system to system
there is no fixed location where they are stored.

The resulting program is the final result, thus it must be in the place
where the user expects it.  You could argue that $BDIR/foo is that
place, but after typing "aap" to build your program, a user doesn't know
if it ended up in build-FreeBSD4_8_RELEASE or build-OtherSystem_8, thus
you can't execute the program without looking carefully where it is.

If you have a different situation it's very easy to specify the
directory where you want your executable to be stored.  You could use:

	:program $BDIR/foo : foo/bar.c
