Merge commit '80521c19'

* commit '80521c19':
  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
