bug#36305: 26.2.90; feature request M-x on immediate left of spacebar for ns-build

[VanL]

The ns-build maps the two modifier keys left of the spacebar for Apple
keyboard without numpad as

 1) M-x         2) s-x 3) left of spacebar ; ns-build

This is different to the X11/GTK and EmacsMac MacPort mappings which are

 1) A-x         2) M-x 3) left of spacebar ; X11/GTK

 1) compose '≈' 2) M-x 3) left of spacebar ; EmacsMac MacPort

Can the ns-build make it easy to set '2) M-x' in harmony with X11/GTK and
EmacsMac MacPort?

Thanks.
