[PATCH] more _make fixes

I'm working on _make a little more, and I noticed that it outputs extra
targets for "VAR := VALUE" lines.  My fix is to add "([^=]|$)" after the
":" in each regex (the "|$" part is just paranoia in case someone put a
useless target without rules or dependencies right at the end of the
file).

Attached is my patch.
