This is interesting. I thought CROSS_COMPILE provided the prefixes to make vars
and that PATH was still needed. But good if this works too so u don't have to
fudge PATH with ARC tools in your env.

No - the default sysroot just works.

Awesome - I presume it ran to completion and builds perf successfully.
Thx a bunch for doing this Arnaldo - CROSS build and uclibc had a tendency to
break here and there so this will catch errors early.
