// This program determines which architectures that this Valgrind installation
// supports, which depends on the what was chosen at configure-time. For
// example, if Valgrind is installed on an AMD64 machine but has been
// configured with --enable-only32bit then this program will match "x86" but
// not "amd64".
//
// We return:
// - 0 if the machine matches the asked-for arch
// - 1 if it doesn't match but does match the name of another arch
// - 2 if it doesn't match the name of any arch
// - 3 if there was a usage error (it also prints an error message)
// Nb: When updating this file for a new architecture, add the name to
// 'all_archs' as well as adding go().
