    build: Modernize build system a bit
    
    Use the tar-ustar option for AM_INIT_AUTOMAKE for better tarballs.
    Do not use AM_MAINTAINER_MODE as it is not recommended by automake
    developers.
    Do not use AC_HEADER_STDC, AM_PROG_CC_C_O as they shouldn't be needed on
    modern systems.
    Pass dlopen disable-static to LT_INIT.
    Require intltool 0.40.6 to avoid various bugs.
    Remove checks for perl and awk, and the useless --disable-rebuilds
    configure flag.
