 Could someone say why does the port set host via this odd method?
 {{{
         if { ${os.platform} eq "darwin" && ${os.major} >= 9 && [sysctl
 hw.cpu64bit_capable] == 1 } {
             set short_host_name
 powerpc64-apple-${os.platform}${os.major}.x.x
         } else {
             set short_host_name powerpc-
 apple-${os.platform}${os.major}.x.x
         }
 }}}

 This hardcodes, in effect, `powerpc64`, for 10.5–10.6 on G5. However, it
 is pretty likely everything is built for `powerpc` in fact (even on 10.5,
 while 10.6 does not support `ppc64` at all).

 For example, I get this:
 ```
 --->  Patching configure: s|__MACPORTS_canonical_host_type__|powerpc64
 -apple-darwin10.x.x|g
 --->  Patching subst-config-vals.in.sh:
 s|__MACPORTS_canonical_host_type__|powerpc64-apple-darwin10.x.x|g
 ```

 But 10.6 aside, in most cases this will be wrong on 10.5.8 too.

 It seems that instead `configure.build_arch` should be used, and that will
 always give a correct result.
