Support make-3.82 and newer
...
make changed its priorties for resolving implicit rules, which causes different
behavior when running "make run-bmark-tests". This patch changes the hex file
rules to ensure they match between the two versions of make.
I've tried this with both make-3.81 and make-4.1, and they both work for me.

Move to a regression Makefile
...
In order to have the buildbot support various types of failures it needs
to run different commands. Rather than modifying the regression script
to have a bunch of arguments I've just gone and made a makefile for
regressions instead.
This doesn't run torture right now because that's broken, but I'll add
support soon.
