I'm not hacking in the Buildroot's gcc package, I'm using local.mk with the
following two lines where /home/naourr/git/gcc is the absolute path to gcc sources:

HOST_GCC_INITIAL_OVERRIDE_SRCDIR = /home/naourr/git/gcc
HOST_GCC_FINAL_OVERRIDE_SRCDIR = /home/naourr/git/gcc

The git bisect is started from /home/naourr/git/gcc and you have to rebuild you
system for each try.

It's a long process (my git bisect took ~10 try.
) because you have to build a toolchain and build the package (and it's
dependencies) that trigger the issue.

Best regards,
Romain
