Sounds reasonable, since there are already a number of other hacking
instructions to follow.

Absolutely; autoconf does a good job at this (and you can use the
resulting configure or config.status to get a good idea of what the code
should look like).

Is it worth writing bootstrap.m4sh, and running it through autom4te to get
the shell selection code from autoconf with minimal effort on your part?
You'd still probably want to check in the generated bootstrap script, though.
