I can cross-compile other software, but nfs-utils fails.

I don't know enough about automake and cross-compiling to be sure, but I think that it doesn't set the CC variable correctly. It does seem to configure correctly though, since it shows the proper compiler being found: "checking for armv7a-cros-linux-gnueabi-gcc... (cached) armv7a-cros-linux-gnueabi-gcc", but then it uses the normal gcc. Thanks for the help! Best, Patrick Dignan
