gnuradio and py-scipy

[Greg Troxel <gdt%lexort.com@localhost>]

It seems math/py-scipy was updated to a version that does not support
python 27, and gnuradio still depends on it.  So perhaps I'm missing
something, but it looks like most of gnuradio will be broken:
Package `py27-scipy-1.1.0' is still required by other packages:
        gnuradio-core-3.7.13.5nb3
        gnuradio-fcd-3.7.13.5nb3
        gnuradio-uhd-3.7.13.5nb2
        gnuradio-digital-3.7.13.5nb2

Perhaps gnuradio does work with 37, and the makefile.common is just
wrong.
