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:

reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,

MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
yann@2173
     5
for e500v2 DPFP support) and will generate appropriate dual-precision

     6
floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to make

     9
sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

    10
from getting into the kernel (which is currently unsupported). At this time,
yann@2173
    11
the kernel build system properly passes those two options, but older kernels
yann@2173
    12
were only passing -mno-spe by default."
