Note that some toolchain contributors package autotools appropriate for toolchain hacking. For instance: - We (toolchain hackers of Gentoo) maintain sys-devel/auto{make,conf}-vanilla in Gentoo for the purpose of toolchain hacking (if you use those, you can set WANT_AUTO{CONF,MAKE} env vars to vanilla-{2.69,1.15}), - Jonathan Wakely maintains a COPR repository for Fedora (and other?) systems: https://copr.fedorainfracloud.org/coprs/jwakely/autotools-gcc/ Perhaps there are similar options for your distribution. Happy hacking, have a lovely day. -- Arsen Arsenović
