[PATCH] Update the return type of gdb_ptrace to be more flexible

[Kamil Rytarowski]

Linux returns long from ptrace(2) and BSDs int.

gdb/ChangeLog:

       * amd64-bsd-nat.c (gdb_ptrace): Change return type from `int' to
       `PTRACE_TYPE_RET'.
       * i386-bsd-nat.c (gdb_ptrace): Likewise.
       * sparc-nat.c (gdb_ptrace): Likewise.
       * x86-bsd-nat.c (gdb_ptrace): Likewise.
