* commit '80521c1997a23e148edf89e11b939ab8646297ca':
  build: allow targets to specify extra objects to link with executables
  swscale: avoid pointless use of compound literals
  libm: add fallbacks for various single-precision functions
  network: use getservbyport() only if available
  network: add fallbacks for INADDR_LOOPBACK and INET_ADDRSTRLEN
  Include sys/time.h before sys/resource.h

Conflicts:
	Makefile
	configure
	libavutil/libm.h
