    linuxloader/image-prelink/image-mklibs: Fix non-standard path prelinking
    
    Prelinking on x86-64 wasn't working out the box as it uses /lib and
    not /lib64 for libs. Prelink was refusing to link as the dynamic loader
    didn't match its idea of the right path. Passing in the --dyanmic-linker
    option avoids this.
    
    We can share code from image-mklibs so abstract that into a new class,
    linuxloader.bbclass.
