Great, thanks.

Interesting. I guess we'll have to experiment a bit with this.

I'm adding Yann in Cc. Yann, have you experienced such thing when
adding bare-metal/newlib support in Crosstool-NG? I've quickly looked
at the Crosstool-NG code, and I don't see the vendor part of the tuple
being skipped specifically for bare metal/newlib toolchains, but maybe
I missed it.

Thanks,

Thomas
