Re: bisecting gnu make

[Paul Smith]

I'm sorry I didn't think of this before, but another option would be to
use the build.sh bootstrapping script, which we provide for situations
where you want to build GNU Make on systems where there isn't already a
make instance available.

This doesn't run make and doesn't require a configure, it just uses a
simple build.cfg file which is generated by configure but you can see
it's trivial and just leave it alone.

As for bisecting across compile errors, compile errors that are
committed are exceedingly rare but it happens: sometimes things work on
my system but not on other systems.  It is something your bisecting
code will have to take into account, and just move past to the next
commit.  There's a "git bisect skip" command for this.
