Marius Strobl ef6f47c4ae Change lwp to int64_t as thr_pread_long() always uses a 64-bit value
in order to account for LP64 targets when cross-debugging on ILP32,
allowing r224683 to compile on ILP32.
Note that thr_p{read,write}_{long,ptr}() still incorrectly use the size
of the respective types on the host rather than that on the target when
accessing the target address space which still needs to be fixed. This
means that r224683 alone may not be sufficient to solve the problem it's
intended to fix when cross-debugging.
