Autoconf will set a default CFLAGS of "-g -O2" if CFLAGS is not set. CFLAGS
was defaulted to "" early in configure to prevent this. A recent commit
ad9ccf660013c208077b1e983d6c824df25ed1cf ("configure: Fix various new
autotools warnings") added AC_USE_SYSTEM_EXTENSIONS, which pulls in the
autoconf CFLAGS check, before we default CFLAGS and thus setting the
autoconf default for CFLAGS. Move the default setting of CFLAGS to before
AC_USE_SYSTEM_EXTENSIONS so that autoconf will see CFLAGS as set and not
give it a default.
