What about replacing DO_SINGLE_STEP, MIPS_SINGLE_STEP and SH4_SINGLE_STEP
(are there more of them?) by a command line option (-singlestep)
which allows setting this at run time?

The increase in execution time can be neglected.

Maybe changing single stepping from the Qemu monitor might also be useful.
