[POWERPC] powerpc vDSO: install unstripped copies on disk

Browse Source 
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.
