Things to do yet:
-----------------
- Fix -Werror for libc6-dev in some architectures (libc6-dev bug?) (see #100047).
- Fix HAVE_INET_NTOP detection on ia64 (why it doesn't work?) (see #105143, #104345).
- Clear issue about libuclmmbase1-dev depending on libc6-dev (¿?).
- Probably libuclmmbase1-dev is really libuclmmbase-dev (without "1")...I'll
  have to reread policy.
