No problem. There are enough cross build cases in esp. where  
configure goes wild.
Please forgive me to not enumerate them fully, because I deal with  
this kind of
problems by circumventing configure in such cases in my build setup
(cat > config.cache <<EOF... basically because autoconf/automake/autogen
isn't reproducible in the real world out there.)
However at least ppc405 with additional TLS support on a 2.4 linux  
kernel
series hosted on a non linux system is one case where configure goes  
badly
wrong.
