The idea is good, but there's an easier way to manage it if you have
the 4.3 or System V make - use the VPATH macro to specify an alternate
path to get sources from.  In the above case, for each bin dir (e.g.
../sun-2, etc.), have a makefile with following line:
	VPATH=../src

You'll have to be careful about a few things, but in general, it's
better than propogating all those symbolic links.
