py37-gobject3 fails for old nm

[rmottola (Riccardo)]

classic issue:

../libtool: eval: line 1720: `/usr/bin/nm -p  .libs/_gi_la-gobjectmodule.o .libs/_gi_la-pygboxed.o .libs/_gi_la-pygenum.o .libs/_gi_la-pygflags.o .libs/_gi_la-pyginterface.o .libs/_gi_la-pygobject-object.o .libs/_gi_la-pygparamspec.o .libs/_gi_la-pygpointer.o .libs/_gi_la-pygtype.o .libs/_gi_la-pygoptioncontext.o .libs/_gi_la-pygoptiongroup.o .libs/_gi_la-pygspawn.o .libs/_gi_la-pyglib.o .libs/_gi_la-gimodule.o .libs/_gi_la-pygi-repository.o .libs/_gi_la-pygi-info.o .libs/_gi_la-pygi-foreign.o .libs/_gi_la-pygi-struct.o .libs/_gi_la-pygi-source.o .libs/_gi_la-pygi-argument.o .libs/_gi_la-pygi-resulttuple.o .libs/_gi_la-pygi-type.o .libs/_gi_la-pygi-boxed.o .libs/_gi_la-pygi-closure.o .libs/_gi_la-pygi-ccallback.o .libs/_gi_la-pygi-util.o .libs/_gi_la-pygi-property.o .libs/_gi_la-pygi-signal-closure.o .libs/_gi_la-pygi-invoke.o .libs/_gi_la-pygi-cache.o .libs/_gi_la-pygi-marshal-cleanup.o .libs/_gi_la-pygi-basictype.o .libs/_gi_la-pygi-list.o .libs/_gi_la-pygi-array.o .libs/_gi_la-pygi-error.o .libs/_gi_la-pygi-object.o .libs/_gi_la-pygi-value.o .libs/_gi_la-pygi-enum-marshal.o .libs/_gi_la-pygi-struct-marshal.o .libs/_gi_la-pygi-hashtable.o   |  | /opt/local/bin/gsed 's/.* //' | sort | uniq > .libs/_gi.exp'

and again helps

if {${os.platform} eq "darwin" && ${os.major} < 10} {
    depends_build-append port:cctools
    configure.env-append NM=${prefix}/bin/nm
    configure.args-append lt_cv_path_NM=${prefix}/bin/nm
}

I put it inside the group block, where other configure commands are

py-gobject3 now builds using meson instead of autotools so this defect, as reported, is no longer pertinent. If there are issues with current version 3.38.0 on these platforms please submit a new ticket with the appropriate documentation.
