This prevents the default HOSTCFLAGS from getting clobbered by flags
passed to configure on the command line.

In particular, avoid to leave around the seg->avf pointer to freed

The avcodec_get_frame_defaults() function is deprecated and its use
doesn't seem required.

user ones) does not allocate edges when this flag is set, which may
