    arm: Use move-if-change for updating regenerated files [PR93548]

    The t-arm make fragment currently uses 'mv' to update some files that
    are automatically regenerated, but this causes problems on read-only
    filesystems if the date stamps are incorrect and the files have not
    really changed.  So use move-if-change instead.

        * config/arm/t-arm: ($(srcdir)/config/arm/arm-tune.md,
        $(srcdir)/config/arm/arm-tables.opt): Use move-if-change.
