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:

    31       Add support for the Signal Processing Engine.  This will set up
    32       the toolchain so that it supports the SPE ABI extensions. This
    33       mainly targets Freescale e500 processors.
    34       
    35       Setting this option will append "spe" to the end of your target
    36       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    37       configure/build system will know to include SPE ABI support. It
    38       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
    39       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
    40       do not need to explicitly add them.
