7e9d8c7256 Merge pull request #40 from ucb-bar/make-3.82
Support make-3.82 and newer

1149a412cc 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.

7209c13338 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.

2f71a3da5a bump up submodule commits to merge commits
Github's PR system doesn't work so well with submodules, since it always
creates merge commits. We should probably avoid using it in the future.
