Ian Jackson requested for this, as it was not originally part of my patch:

http://lists.xen.org/archives/html/xen-devel/2012-03/msg00762.html

But I don't really think it's necessary/useful for the end user.

Autoconf does not provide a macro to write to config.log only, but
there's a little trick:

http://ac-archive.sourceforge.net/doc/tricks.html

I'm going to change those messages so that they are only written to
config.log but not the screen.

Is the configure script working correctly under ARM? I haven't been
able to get my hands on any ARM board, but I have a rpi reserved that
I hope doesn't take long (I could also use Qemu I know...).
