What about setting this in  /etc/ld.so.conf.d/grass.conf  and running
ldconfig (as root)?  I have wrongly set there  /osgeo/grass64/lib
instead of  /osgeo/grass64/dist.x86_64-unknown-linux-gnu/lib.

I can see the plugin for 64 now. However, trying to open a (new) Mapset,
returns  "The config file /osgeo/QGIS/grass/config/default.qgc) not
found.".  And the GRASS toolbar icons (as well as for other toolbars)
are (partially or completely) invisible.

So, it is wrong to provide both paths for 64 and 70 at the same
time in /etc/ld.so.conf[.d/somefile.conf].

Thank you, Nikos
