[git commit] buildsys: tweak KCONFIG_CONFIG export

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=0a513103bf2a80787ec4c7064570d08ad36881aa
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

0c3eb2da578bc7ba2e74d240e3249dce62ec725e moved KCONFIG_CONFIG around and
that broke propagation of config-settings to the testsuite. Fix that.
