Implemented 2003-11-22 for ppc. Even documented. :-)
@item .machine "string"
This directive allows you to change the machine for which code is
generated. @code{"string"} may be any of the -m cpu selection options
(without the -m) enclosed in double quotes, @code{"push"}, or
@code{"pop"}. @code{.machine "push"} saves the currently selected
cpu, which may be restored with @code{.machine "pop"}.
