Subject: [PATCH] README-hacking: re-configure from scratch during bootstrap.
MIME-Version: 1.0

When building autoconf from a git checkout, recommend running
‘make distclean’ and a second ‘./configure’ after regenerating
autoconf’s own configure script using the just-built autoconf.
If one only runs ‘make check’ at that point, some configure-time
tests will not be repeated using the new code, such as detection
of a “better” shell.
