It is still specific per source since the ${.TARGET} contains the source
name (i.e. foo.c -> foo.o):

__BUILDSEED=    ${BUILDSEED}/${__INITSEED}/${.TARGET} 

It does not contain *all* the sources like before, but one source should
be enough, or not?

Anyway, the fix to remove the files that contain relative paths should
make things deterministic again; I just wanted to make sure that they
were, and keeping this simple (using the timestamp) sounded like a good
idea (unless you need a better guarantee of uniqueness than the single
source name).
