bug#13761: FAIL: t/objc-megademo.sh (OS X 10.6)

[Daniel Macks]

Building automake on OS X 10.6 with autoconf-2.69 installed, I get a self-test 
failure:

FAIL: t/objc-megademo.sh

Same results with automake-1.12.6 and 1.13.1 (and same as one of the ones 
reported in Bug #11618). The build process in t/objc-megademo.log looks normal, 
up until:

./t/objc-megademo.sh: line 344: 95507 Illegal instruction     ./play > got

from am-1.12.6 (am-1.13.1 is same except it's line 366). Running 
t/objc-megademo.dir/play from the command-line gives:

[Hello C, world C]
[Hello C  , world C  ]
Illegal instruction

That's all using the default 64-bit mode (-arch x86_64). If I force 32-bit mode 
 (using "-arch i386" with all compiler calls), it still fails, but the 
command-line output is different:

[Hello C, world C]
[Hello C  , world C  ]
objc[44708]: Hello_ObjC: Does not recognize selector forward::
Illegal instruction

It passes on 10.7.

 I don't know much about objc, but can try any ideas to debug or solve that 
someone has.
