Maybe related, but maybe not: gpsd (from feeds/packages) won't compile  
due to a wrong include path. It uses the hosts 'ncurses6-config --libs  
--cflags', which (on my system) boils down to

-lncurses -ltinfo
-D_GNU_SOURCE -I/usr/include/ncurses

The libraries are probably fine, but the include directory from the  
host is not such a good idea. Looking at the compilation error, it  
looks like it will build fine without the --cflags, so that's what I  
tried. That seems to do the trick. Is this what we would expect here?  
Do we really trust the ncurses6-config from the host to come up with  
the proper --libs and --cflags?
