- Change the way libdhcp4client is compiled (patch main source, create new
        Makefile rather than copy and patch code after main patches)
    - Fix up problems generating compiler warnings
    - Use 'gcc' for making dependencies
    - Pass -fPIC instead of -fpie/-fPIE in compiler flags
    - Combine the extended new option info changes in to one patch file (makes
        it easier for outside projects that want to use dhcdbd and
        NetworkManager)
