 Since we don't really want to pass any flags from Buildroot down to the package
build systems, perhaps we should just set

override MAKE := make <jlevel stuff>

at the top of package/Makefile.in? I've done a quick test, and it seems to fix
the boa issue at least.

 This would revert the following commit though:

commit 4705b600764c683e934da7db54f7971a3c647e8a
Author: Ulf Samuelsson <ulf.samuelsson at atmel.com>

    Ensure we use host 'make', even when building 'make' in buildroot

but that doesn't explain why it is not wanted to use the Buildroot-built make...
