1.6.3 build failure on AIX 5

[Damian Hazen]

Hi -

This is a follow up to  
http://mailman.mit.edu/pipermail/krbdev/2007-August/006093.html 
concerning build failures on AIX.  A few weeks ago we opened RT ticket 
5770 with an attached patch to address.    I just verified that building 
1.6.3 on AIX using xlc still fails w/o the patch, and that the patch in 
the ticket is still applicable.   Could someone please take a look?  
More info for the failures follows.

The failure is triggered because libraries with  .so extensions are not 
searched for when linking unless the -brtl flag is passed in.  This will 
be a problem for external applications linking against the kerberos 
libraries as well.  The patch is intended to follow Ken Raeburn's 
suggestion to differentiate between plugin and shared object extensions 
in shlib.conf for AIX 5, and removes the runtime link flag when 
generating shared libraries and plugins.  I think that the cases in 
shlib.conf for *-*-aix4*) and *-*-aix5*)  could be combined, but I don't 
have an AIX 4 system to validate this.

The second failure is when generating db2.so:

We addressed this by removing the special case for AIX in the makefile 
fragment.
