Oh, yes, sorry, my wording was maybe confusing (english is not my
native language). To make external toolchain work, --sysroot *must* be
passed to every gcc/ld invocation, but it's clearly not the case in
many non-autotools packages.

I'm also a bit puzzled by the problem you had on Busybox, since I'm
definitely able to build it with 2010.02, as it is, with a Crosstool-NG
external toolchain (but not with a Buildroot external toolchain). I'll
try to reproduce.
Regards,
Thomas
