MIPS ptrace build fixes
Since Pedro's ptrace cleanups, the MIPS buildbot compilation fails. Code in MIPS native uses ptrace with 3 arguments, where ptrace requires 4. When looking at the definition of ptrace in /usr/include/sys/ptrace.h, it shows that it takes a variable number of arguments. The wrapper macro in nat/gdb_ptrace.h takes a fixed number of arguments (4). That would explain why it used to work and stopped. I am pushing this as obvious, tell me if there is any problem. I built-tested this with a MIPS toolchain (ct-ng), but I don't have any setup to test it. At least it should put back the buildbot builder in a better shape. gdb/ChangeLog: * mips-linux-nat.c (write_watchpoint_regs): Add NULL as ptrace's 4th parameter. (mips_linux_new_thread): Likewise. * nat/mips-linux-watch.c (mips_linux_read_watch_registers): Likewise. gdb/gdbserver/ChangeLog: * linux-mips-low.c (mips_linux_prepare_to_resume): Add NULL as ptrace's 4th parameter.
