[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.
