package/pkg-autotools: don't use config.site when cross-compiling

On fedora 20 64bits host, the file /usr/share/config.site contains
a fix for installing libraries into /lib/lib64 on 64bits systems
that redefine libdir in the generated Makefile

For safety and avoid the bug #7262 [1], disable loading this file
when running the configure script for the target and the host.

Note: configure scripts generated with autoconf < 2.65 will source
the /dev/null and print this line:
"configure: loading site script /dev/null"
