    [build] Fix linking with pedantic linkers
    
    - Explicitly link to x11 on gnome platform.
    - Explicitly link evince (shell) with libm.
    - Add explicit -lm flag for libevview and backends, so that we do not
      depend on gtk+-2.0's .pc file to pull this flag in.
    
    Fixes bgo#609895.
