libselinux,libsemanage: fall back to gcc in exception.sh

clang does not support -aux-info option. When exception.sh is run with CC=clang, use gcc to build selinuxswig_python_exception.i and semanageswig_python_exception.i. This does not solve the issue of building libselinux and libsemanage Python wrappers on a system without gcc. However parsing the result of "gcc -aux-info" is easier than parsing the header files so stay with this command at least for now. Signed-off-by: Nicolas Iooss <[email protected]>
