Looks OK.  NB the -E options forces a clean rebuild of everything.  In
your case -e is faster as it forces a clean build only of mythtv.

It's safer to cp the archive to the RPi and expand that.  However, for
speed, if only a few files are changed, then I use:
        
rcp -p mythinstall/lib/libmyth*-0.27.so.0 pi at raspberrypi:~/mythtv-rpi/lib/
rcp -p mythinstall/bin/myth{avtest,frontend} pi at raspberrypi:~/mythtv-rpi/bin
rcp -p mythinstall/lib/mythtv/plugins/* pi at raspberrypi:~/mythtv-rpi/lib/mythtv/plugins/
