I am not sure to understand correctly. If we modify GNU Make 3.81 (by 
applying a patch) that is distributed in our sources, we redistribute it 
under the terms of GPLv2. No? Do you mean that this line:
# if _GNU_GLOB_INTERFACE_VERSION == 1 || _GNU_GLOB_INTERFACE_VERSION == 
2
is GPLv3 licensed? And therefore we should redistribute the whole GNU 
Make code under the terms of GPLv3?
This line can be found here: 
https://git.busybox.net/buildroot/tree/package/make/0001-configure.ac-Support-GLIBC-glob-interface-version-2.patch?id=157231405d219e484aa3829acff23569f6a60d00
in a project that is GPLv2 distributed.

I don't want to be too many insistent. Could we imagine putting GNU Make 
4.2.1 under external/gpl3/gmake/dist?
