The external toolchain stuff? That's afaik known to not work.

Strange, so the packages don't respect CFLAGS / LDFLAGS?

And what about the 10s of other libraries we have? To me it seems like
something else is broken in the external toolchain stuff, and this is
just pampering over it.

The kernel headers are pretty closely related to the C library, and
hence the toolchain, so my initial thought is that it sounds wrong.
But if you want to work on making the external toolchain stuff less
broken AFTER the release, then that's fine as long as it doesn't add
too much complications and the internal toolchain stuff keeps working.
