$NetBSD: patch-configure,v 1.3 2019/06/02 09:48:11 tsutsui Exp $

o Handle properly sh3, evbarm, and arm64 ports on NetBSD.
o Fix CPU family detection on NetBSD with /proc mounted with "-o linux"
  (please see also kern/25076).
o Delete not needed -Iffmpeg from the CFLAGS.
o Fix a bug which broke the detection of a lot of X11 libraries.
o Add necessary libs for aalib support even if the aa option is turned on with
  --enable-aa.
o Add support for dvb capture on NetBSD.
o Explicitly enable PIE to avoid text relocations on NetBSD/i386 8.x
o use /dev/audio instead of /dev/sound for OSS audio device for NetBSD
  (see PR/54229) and OpenBSD (no /dev/sound since 6.1)
