AHCI/BFS: fixed temporary trim debug output.
Add missing texinfo to bootstrap package list.
Don't try to put findutils-commands on bootstrap image.

* findutils has been moved out to a haikuport, so the commands are no
  longer known to the build system
Adjust libnetwork.so to no longer depend on libbe.so.

* Libbe is not available when cross-building the *_bootstrap packages,
  so no libnetwork could not be used either, which made building 
  anything network-related impossible.
* The only code in libnetwork that requires libbe is the notification,
  so I moved that over to libbnetapi. Non-C++ applications can't use
  the notification calls anyway, as their interface is C++-only.
Add libnetwork.so to stage1 of bootstrap build.
Add curl to bootstrap package list for x86_64.
Put curl on every image, as it is required by the haiku package.
Correct typos (wrong primary architecture) in comment.
Update gcc4 version in haikuports.cross repository.
x86: Update gcc and binutils packages.

- Mainly needed to enable C++11 support in gcc.
