From: Marc-André Lureau <marcandre.lur...@redhat.com>
Since commit efc6c07 ("configure: Add a test for the minimum compiler
version"), QEMU explicitely depends on GCC >= 4.8, we could thus drop
earlier version checks. Except clang advertizes itself as GCC 4.2.1.
Since clang doesn't support gnu_printf, make that case explicitely and
drop GCC version check.
