Hi Eddie, 

Click does nothing wrong, it's just that OpenWRT just happens to use
"make" as meta build system, so the Makefile here is totally OpenWRT
specific, it only works as an include to OpenWRT's core makefile, and
actually calls Click's make underneath...

It currently builds userlevel only, since back when we wrote it, there
was no patchless....
