The kernel truly builded by clang, but the newvers.sh picked up the wrong compiler to set compiler_v variable.

compiler_v=$($(${MAKE:-make} -V CC) -v 2>&1 | grep 'version')

kern.compiler_version: gcc version 4.2.1 20070831 patched [FreeBSD]

>How-To-Repeat:
1) install a clean 9-STABLE
2) add the line upper in src.conf
3) make buildworld kernel
