 The problem with this approach is that you'd have to create identical
 files for every alias for an architecture uname can output on any
 system supported by pkgsrc, resulting in a big number of files that
 are all the same.
 
 A better approach would be to replace known arch strings in the uname
 output, like lib9/Makefile already does for all x86 architectures.
 It replaces i.86 by 386.  We could do the same for 'macppc' -> 'ppc'
 and also 'amd64' -> 'x86_64', since it doesn't build on amd64 either.
 
 See the attached patch for concrete example.
