gdb.trace: Fix write_inferior_data_ptr on 32-bit big-endian machines.
Noticed and tested on 31-bit s390. This bug caused completely broken
fast tracepoints.
gdb/gdbserver/ChangeLog:
* tracepoint.c (write_inferior_data_ptr): Cast to uintptr_t, so that
it works properly on big-endian machines where sizeof (CORE_ADDR)
!= sizeof (void *).
