It is not make which is crashing -- it is libfakeroot. Try the
same build command with --rootcmd=sudo, and the build works just
fine. I even tested with setting CONCURRENCY_LEVEL in
/etc/kernel-img.conf, in case sudo was stripping off the
DEB_BUILD_OPTION
So the problem is not in make or kernel-package, it is in fakeroot.

Here is the scenario:

Yes.

Perhaps. 11.XXX kernel-package was very unfriendly to parallel
compilation, with the current 12.XX all targets except buildpackage can
be compiled in parallel. This has cause a little bit of a slowdown, as
the build assures synchronization.
