[RFA] Fix gdb compilation error in opcodes/dlx-dis.c with --enable-targets=all for mingw64

["Pierre Muller" <pierre.muller@ics-cnrs.unistra.fr>]

  'unsigned long' type is 4-byte
on x86_64-w64-mingw systems, which is less
than a pointer size.
  After some searching, I found bfd_hostptr_t
type that is supposed to have the correct size of a host 
pointer.

  I tested the patch below by compilation 
with --enable-targets=all configure option
for i386-cygwin, x86_64-w64-mingw and x86_64-unknown-linux-gnu.

  I also ran the gdb testsuite on x86_64-unknown-linux-gnu
(gcc10 machine from gcc compile farm).
  No regression found.

  I don't know who is the main maintainer project
binutils or gdb?

  Who can give me the approval for this patch?
Is the patch itself OK?
