[Octave-bug-tracker] [bug #53099] mkoctfile confused by unknown options followed by source file arguments

[marco atzeri]

Follow-up Comment #12, bug #53099 (project octave):

I think I hit a different version of the original problem when trying to build
*image-2.8.1* with *octave 4.4.1* on cygwin.  I missed to note the problem
before but it was also present.

The problem does not appear on normal *pkg install* but only on buildbot-like
enviroment that produces invocation with very long list of argument to
*mkoctfile*.

Failing case: instead of producing a conndef.oct a connectivity.oct is
requested to g++

Workaround: a simple `-v` is added to the invocation
