I think that's a good idea.
README.md says that the only mandatory variable is TARGET. I assumed
c,c++ only was default.

I had a quick look. Patches apply with two very minor adjustments, I've
attached the edited patches. I rebuilt arm-linux-musleabi but haven't
used it in anger yet. Is there a way to easily check all targets?
Also, is there a way to get linux headers installed with the toolchain
(like crosstool does)?
I use 4.9.3 for building old arm 2.6 kernels and haven't had a problem
with it yet.
