Thanks for trying it out. Well, this is a general incompatibility of the SDK's environment
setup script with Kbuild then. I am wondering why they decided on not having a default
--sysroot. Raising the issue upstream could shed some light on this and perhaps result
in a fix. I don't think there is anything to fix here at the barebox side.

FTR: we use meta-ptx extensively and AFAIK we haven't run into this issue. It only
popped up when using the SDK build, so bitbake seems to do the right thing in that case.

Cheers,
Ahmad
