Indeed no, and besides, there are so many different commands being run
before running configure. You can get a peek at it and see the various
sneaky things we do:

    $ grep -E '_PRE_CONFIGURE_HOOKS' $(git grep -l -E '\$\(eval \$\((host-)?autotools-package\)\)')

One of the funniest being libtool, for which we need to carefully touch
some files to make configure believe they are up-to-date.

There are a bunch of packages running just 'autoconf' because they are
not in fact real autotools packages; they are just using autoconf, not
automake, so they do not autoreconf nicely.

Then we have at least one package that needs to chmod +x configure.

And all the various 'mkdir m4' we have here and there...

So, in the end, I stand by my position: no need to make that part of the
infra, the variance is too large.

Regards,
Yann E. MORIN.
