Fixes for Mac OS X/x86 building/running

[Jonas Maebe <jonas dot maebe at elis dot ugent dot be>]

Hello,

Archer (archer branch) is currently broken on Mac OS X/x86. The  
attached (minor) patches fix this:

* darwin-nat.c.patch fixes compilation errors due to some missing  
"struct target_ops *" parameters. Probably caused by:

commit be44ac148163ced0dde7b8ff23c8f1cc49efa106
Author: Pedro Alves <pedro@codesourcery.com>
Date:   Mon Feb 23 00:03:47 2009 +0000

* machoread.c.patch fixes a crash caused by a missing function pointer  
field (sym_read_psymbols) initializer in the middle of macho's struct  
sym_fns (so the subsequent function pointer initializers were all  
shifted). I've simply copied the elfread.c implementation of  
read_psyms (because it appeared to be generic) and it seems to work  
fine (if it's called at all). I guess this needs to be solved in a  
better way though (maybe a NULL pointer would be enough). I'm not sure  
why I didn't see this crash when I built gdb last time (on January 17  
from the archer-jankratochvil-vla banch), as this field was already  
added on 2008-09-09 (by Tom Tromey) according to git.

With these two patches applied, the Mac OS X build and works fine  
again on i386 (at least in my cursory testing).
