i have scripts around "git-bisect run" (which are custom to my test environment so not generally applicable), but perhaps it would be useful to extend it a little bit to have automatic support for "build error bisection". 99% of the FOSS packages that developed under git can be built via "make". So could you perhaps add fully automatic bisection support that is driven by doing "make" in the current repository?

Currently, in the Linux kernel, if i do this:

 $ git-bisect run make -j64 kernel/

it fails with:

 running make -j64 kernel/
   CHK     include/linux/version.h
   CHK     include/linux/utsrelease.h
   CALL    scripts/checksyscalls.sh
 bisect run failed:
 bisect_good exited with error code 1

although the command "make -j64 kernel/" returns with 0.

i have to write a script around "make -j64 kernel/" to get this to work 
- it would be nice to have this "out of box".
