Not easily -- the machine has spent its time running build.sh from the
date of the last sucessfull kernel (July 12th) with a couple of
restarts of the build until august 8th. Normally I turn it off after a
build cycle, but noticing the recent bunch of mips updates, I decided
to give it another turn the the result mentioned...

I can probably restore my machine into working order by doing a
cross-build on another machine and then recreating /usr/bin and
whatever else has been lost.
At that stage I can try patches suggested by and/or rebuilding a debug kernel.

For reference I enclose my kernel configuration file:
