PATCH: 3.1.6-dev-20: runtime determination of MACHTYPE

[Clint Adams <schizo@xxxxxxxxxx>]

This patch allows zsh to determine MACHTYPE at run-time, rather
than from the configure results of the build-machine, assuming
uname(2) is available.

I assume that the overhead is low enough that no one will feel
the need to disable this.
