Subject: x86_64 vDSO: install unstripped copies on disk
From: Roland McGrath <roland@xxxxxxxxxx>
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.
