Make the gdb.objc tests compile

Browse Source 
The gdb.objc tests haven't compiled in years.  This patch fixes this,
based on a comment in bug 31671.

I don't know whether this approach works with the clang implementation
of Objective-C.  However, it does work with GCC, provided that
gnustep-base is installed.
