Demo project for autoconf build error when cross-building from macOS to iOS

This project demonstrates what appears to be a bug in the autoconf Conan recipe when cross-building from MacOS for an iOS host. To reproduce, check out the project and run conan install . --build missing -pr:h ios-profile from the root directory. The resulting build failure is autom4te: error: need GNU m4 1.4 or later: /usr/bin/env m4 despite a previous step building m4 1.4.18 and setting an environment variable to its path.
