64 bit system libs

[Anthony Shipman]

On my 64-bit openSuse system I get

$ pkg-config --static --libs QtMultimedia
-L/usr/lib64 -L/usr/X11R6/lib -L/usr/lib64 -L/usr/X11R6/lib -L/usr/lib64
-lQtMultimedia -lQtGui -lQtCore -lpthread -lasound -lQtGui -lQtCore
-lpthread -lgthread-2.0 -pthread -lglib-2.0 -lpng -lz -lfreetype
-lgobject-2.0 -lglib-2.0 -lSM -lICE -lXi -lXrender -lXrandr -lXfixes
-lXcursor -lXinerama -lfontconfig -lfreetype -lXext -lX11 -lm -lQtCore
-lpthread -lz -lm -ldl -lgthread-2.0 -pthread -lglib-2.0 -lrt 

Should the lib64 system libs be filtered out?
