Title: samba: add autotools to fix dep error on Lion

Samba calls autogen.sh, but never had any deps on autotools.
This causes a build error for Lion users who never installed them.
Add the standard deps on automake & libtool if XCode >= 4.3
Tested on with Clang and llvm from XCode-4.3.3.

Fixes #13188
