    configure.ac cleanups
    
    - replace the obsolete AC_GNU_SOURCE with AC_USE_SYSTEM_EXTENSIONS
    - remove the following macros whose results were unused:
      - AC_PROG_INSTALL
      - AC_CHECK_HEADERS(fcntl.h paths.h sys/ioctl.h sys/time.h syslog.h unistd.h)
      - AC_TYPE_MODE_T
      - AC_HEADER_TIME
      - AC_CHECK_FUNCS(select socket uname)
      - AC_C_BIGENDIAN
    - remove the following obsolete macros (not relevant on non-historic systems):
      - AC_PROG_GCC_TRADITIONAL
      - AC_FUNC_MEMCMP
