    cf: Prevent default CFLAGS in OPENAFS_PATH_CC
    
    Commit dba6ec9548ab (cf: Set CC before calling AC_PROG_CC) moved our
    logic for preventing a default CFLAGS from the top-level
    configure.ac/configure-libafs.ac into OPENAFS_CONFIGURE_COMMON. This
    doesn't work, because OPENAFS_CONFIGURE_COMMON calls
    AC_USE_SYSTEM_EXTENSIONS, which effectively runs the compiler and sets
    default CFLAGS at the beginning of OPENAFS_CONFIGURE_COMMON.
    
    This means that if the user doesn't specify any CFLAGS, autoconf will
    set our CFLAGS to the default of '-g -O2', which can break various
    environments. (For example, --disable-optimize no longer works, because
    that flag only controls the OPTMZ var, and doesn't touch CFLAGS.)
    
    To fix this, move our logic for preventing default CFLAGS into
    OPENAFS_PATH_CC, which is explicitly called before
    OPENAFS_CONFIGURE_COMMON so we can set the compiler before autoconf sets
    its defaults. This should ensure that we are setting CFLAGS before
    autoconf does; otherwise, we're also probably not setting CC early
    enough, either.
