... and there's a use in gnulib-common.m4, and at least a couple of
dozen uses directly in various configure.ac's according to
https://codesearch.debian.net/search?q=%5C%24as_echo%28%3F%3A_n%29%3F%5Cb+-pkg%3Aautoconf+path%3A.*%2F%28%3F%3Aconfigure%5C.%28%3F%3Aac%7Cin%29%7C%5B%5E%2F%5D%2B%5C.m4%29%24+-path%3A.*%2Fax_pthread%5C.m4%24+-path%3A.*%2Fgnulib-common%5C.m4%24&literal=0
so yeah I think we do need some backward compatibility here and maybe
a deprecation warning if we can swing it.
