Subject: autoreconf: support newer archs

Update to more recent version of configure script to support more
new architecture types like RISCV64. Tools in use ATM:

autoconf-2.71-3.fc37.noarch
autoconf-archive-2022.02.11-3.fc37.noarch
automake-1.16.5-9.fc37.noarch

Resolves https://bugzilla.redhat.com/show_bug.cgi?id=2118243
