 Input string is an architecture name to canonize. The function recognizes many variants, for example:
 C<32e>, C<Intel64>, C<Intel(R) 64>, etc. Returned string is a canononized architecture name,
-one of: C<32>, C<32e>, C<64>, C<arm>, C<ppc64>, C<mic>, or C<undef> is input string is not recognized.
