Thanks.  Yes, unfortunately it's a dependency of a lot, making it 
a staging package.

I didn't rebuild all dependents before pushing but I did build 
several packages including u-boot-pine64-lts (on x86_64) as a 
smoke test.  I also verified that lz4 with 
--target=aarch64-linux-gnu actually builds for aarch64 now.  I 
think it's safe.

If anything were to break I'd say it must have been broken before, 
but do let me know if it happens.

Each package using CC=gcc?  There are currently hundreds; I don't 
think that's what Ludo' meant.  Do hope to have it down to tens 
soon...

Kind regards,
