My understanding was that the current patch (1) makes not using
lingcc the default for ARM, and (2) makes it the default for ARM for
all too chains.

Please show me how to activate the feature from the command line, as
I seem to have missed this option (and the documentation for it).

But ARM is just one out of many different  architectures,  and  there
are  eventually  (sufficently)  sane  ARM tool chains available, too.
This is the default case, and shall remain it.

For broken tool chains (ARM or other) the feature can be activated
(when running make).


Best regards,
