--enable-64-bit-bfd. Basically the issue happens when dealing with "bl"
instructions: GDB does branch destination calculation and (wrongly)
sign-extends the PC. Here is a piece of his original message explaining
the problem:

Anyway, the fix is simple and Andrew himself provided it for us. It
took a while for me to figure out how to trigger the bug (in order to
write a testcase for it), but I finally made it.
The attached patch fixes the problem (by casting to `unsigned long'
instead of just `long'), and also includes a testcase to reproduce the
issue.
gdb/ChangeLog:
2013-04-22 Andrew Haley <aph@redhat.com>
* arm-tdep.c (BranchDest): Cast result as "unsigned long",
instead of "long".

* gdb.arch/arm-bl-branch-dest.c: New file.

* ctf.c (ctf_fetch_registers): Change the type of 'regs' from
'char *' to 'gdb_byte *'. Cast the return value of
'bt_ctf_get_char_array' to 'gdb_byte *'.
"signedness" is more typical.

This enables -Wpointer-sign by default.
I've checked that --enable-targets=all builds fine with the following
as --host, on x86_64 Fedora 17 --build:
x86_64 GNU/Linux
i386 GNU/Linux
i386 MinGW-w64
i386 msdos/djgpp
OK?

This is the remaining issue impeding GDB to build with "-Wpointer-sign
-Werror" with Fedora 17's i686-w64-mingw32 cross toolchain.
