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 Attached is a patch to add __attribute__ ((noinline)) to

     5 call_gmon_start.

     6 

     7 Without this patch, the sec script that processed initfini.s removes a

     8 part of inlined call_gmon_start, causing undefined label errors.

     9 

    10 This patch solves the problem by forcing gcc not to inline

    11 call_gmon_start with __attribute__ ((noinline)).

    12 

    13 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
