It's probably worth amending the out-of-tree build instructions to add
$(ROOTDIR)/tools to the path, in the Makefile.

Something like

PATH += $(ROOTDIR)/tools

in the sample Makefile shoudl do the trick.  Do you mind testing this
and confirm if it works, and I'll update the wiki?

Hmm, sounds bogus.  ucfront is not involved in the kernel build at all,
it's only for libs and apps.  I'm not sure why there should be any
involvement of it here.  You may have already worked around this, but if
not I'd suggest doing a make clean and starting fresh with the kernel.
Certainly haven't seen anything like it at this end.

Regards,

John
