The development environment (cross-compiler, cross-binutils, etc.) has
been supplied by LG, and at least it's the same cross-compiler used to
build the original kernel

As they are in the same source tree and I replicated the functions
performed by the build scripts there, I suppose they are the same.
In fact, according to the sourcecode faq
http://gpl-violations.org/faq/sourcecode-faq.html
that's what they have to provide to be in compliance.

I've done my best with the things that have been provided to me, yes.
If I've not been provided with all the necessary pieces, then LG is not
in compliance.

Frankly, I'm going to give up. Maybe that's what LG wants.
