    [POWERPC] powerpc vDSO: install unstripped copies on disk
    
    This keeps an unstripped copy of the vDSO images built before they are
    stripped and embedded in the kernel.  The unstripped copies get installed in
    $(MODLIB)/vdso/ by "make install".  These files can be useful when they
    contain source-level debugging information.
