scripts: unset CONFIG_SITE

Some distributions (eg. openSUSE 12.1) systematically export
the CONFIG_SITE environment variable to point to a custom
script setting misc paths for ./configure.

This can, and does, break when cross-compiling for architectures
that are not supported by this script.

The simple workaround is to unset this variable.
NB: buildroot has a similar fix:

     4 Hello,
     5 
     6 I have SEGV at busybox's telnet with uClibc-0.9.30.
     7 It seem the current uClibc-trunk has the same problem.
     8 
     9 Thanks,
