I do think this idea presents a chicken and egg problem though - the
shell is needed by configure, but will not be available until it has
been built by a bootstrap.
The shell could be built before running the configure.
Unfortunately, I think Lennart's idea is not practical: a typical
configure script exercises many advanced shell features, and so
crafting a shell that could run it will need to implement most of the
features we have in Bash. Such a shell will be neither small nor
portable, because a Posix shell needs quite a few Posix features.
