The patch at the end of my mail is the latest state of the code.

There are two things I need help with.  The first is getting it to work,
obviously, and the second is getting it into an acceptable state.  It's
likely that that does change the behaviour for all ports.  When our MIPS
support was added originally no consideration was given to anything but QNX.
I don't think having the support rolled back into the GNU tree was
considered at the time.
