The issue's not GDB support, but kernel support. I've seen several
proposals to expose watchpoint registers over ptrace on MIPS, but so
far none of them have merged. The usual place they bog down is how to
explain to GDB what capabilities are available; x86 has it easy,
there's basically only one type.
