Doesn't look harmful in principle, but it seems to have worked until
now without CROSS_COMPILE="$(TARGET_CROSS)". Can you expand the commit
log by explaining in which case you have seen errors, and which errors.
The linux-headers package is used daily to build toolchains by all
Buildroot users, so I'd like to understand how your situation is
different. Is it that the ARC kernel headers need something special?
But we are building ARC toolchains everyday in the autobuilders, with
no problem. That's why I'd like to have more details.
