0136e467ea AIX 32-bit core loading, high section addresses. 
I noticed GDB was failing to enable threading support for 32-bit AIX
cores.  I traced it to failure to read variables from libpthreads.a.
The issue is that data for that library is loaded at a high address,
and bfd is sign extending the section addresses:

 (gdb) info files
 Symbols from "/home/palves/crash".
 Local core dump file:
	 `/home/palves/core', file type aixcoff-rs6000.
	 0x2ff22000 - 0x2ff23000 is .stack

	 0xf06dafe0 - 0xf07b3838 is .data in /usr/lib/libc.a(shr.o)
	 0xf0751e94 - 0xf07b3838 is .bss in /usr/lib/libc.a(shr.o)

Notice:
	...
	0xfffffffff0298000 - 0xfffffffff029bfcc is .data
	...

Those are the bfd section start/end addresses.  It't not visible here:

         ...
	 0xf0298000 - 0xf029bfcc is .data in /usr/lib/libpthreads.a(shr_xpg5.o)
         ...

... just because GDB trims that number to 32-bit when printing.

GDB then fails to find the memory for libpthreads.a variables in the
core, and falls back to reading it directly from the executable (which
yields the values as originally initialized in the code).

E.g.:

 (gdb) p &__n_pthreads
 $2 = (<data variable, no debug info> *) 0xf074fda8 <__n_pthreads>
 (gdb) p __n_pthreads
 $1 = -1

That should have returned 2 instead of -1.

	PR gdb/16696
	* rs6000-core.c (rs6000coff_core_p): Cast pointers to bfd_vma
	through ptr_to_uint instead of through long.
