Fixing samba build on Snow Leopard

[Matthieu Patou]

Hello Tridge,
Can you have a look on this 3 patches:

1619b50 waf: introduce reverse logic for allowing unknown symbols
177c832 waf-build: Separate the notion of public dirs for extras includes
940cac5 s4-heimdal: remove replace dependency

They are at 
http://git.samba.org/?p=mat/samba.git;a=shortlog;h=refs/heads/buildfixes

We need this patches to address 2 pb while building samba4 on OSX 10.6 
(snow leopard):

1) rkpty needs openpty function that is declared in /usr/include/util.h 
on mac (it's in /usr/include/pty.h on Linux), the #include in the 
lib/roken/rkpty.c is correct but our include search path is not as we 
add -Idefault/include/public -I../include/public and in this folder we 
have a completely unrelated util.h header that get included (but didn't 
provide the function). After talking with jelmer it seems that I 
understood that we should not add our public header in the search path 
when building heimdal, that's what the patch 177c832 do, it split the 
EXTRA_INCLUDE to put the public header folder apart so that we can have 
the option to add or remove them
2) we have unresolved symbols when linking libutil-samba-common, this is 
due to the fact that -Wl,-no-undefined do not work on OSX 10.6 so I made 
1619b50 to have a linker option to add to tell him to not exit with an 
error if there is unknown symbols (just the opposite ok the 
-no-undefined linker flag).

On my computer it works pretty well now.
The last one is a cosmetic one: I removed a dependency that is not needed.

George: can you try to build on your mac with my Tree and let me know !

Matthieu.
