Somewhere along the way this got broken, this line needs to be #if
defined(__i386). I'm failing to build on x86-64 with this change.

   static const unsigned kNumDebugRegisters = 8;
   debugreg_t dregs[8];
+#elif defined(__ARM_EABI__)
+  // Mimicking how strace does this(see syscall.c, search for GETREGS)

 #endif
