yes, I am just asking to make it *optional*, i.e. provide an autotools
option to build bison without examples.

For Gentoo, this started in 2015 with https://bugs.gentoo.org/538300.

The bison package is in our @system set, i.e. it will be required
whenever you bootstrap Gentoo. Thus, because building without perl would
fail at this point, this is a problem for us.

So we made examples and therefore perl an optional dep allowing us to
build bison as part of our @system set during bootstrap without any

It would be totally fine for us to keep this option enabled by default
in bison, i.e. nothing would change for any user. But it would allow to
disable it during our bootstrap without patching bison all the time on
our own (because like said, this package is used during bootstrap, we
cannot even normally patch and re-run autoconf, so we also need to patch
autoconf files and hack around, see
