Update to v087r01 release.

byuu says:

Changelog:
- fixes ARM core unaligned memory reads (fixes HNMS2 AI, hopefully completely,
  we'll see though) [Cydrak]
- ARM 40000010 writes are now connected to d2 rather than the timer
- ARM bus_readbyte() removed (would love to do the same for writebyte if
  we can ... then we can drop back to bus_read + bus_write only)
- USART with IObit set acts as a regular gamepad now (don't have this
  hooked up with real hardware, but oh well, it's technically possible
  so there's that)
- OpenGL/GLX will use 30-bit when you have a 30-bit display; no need for
  config file video.depth anymore
