One of the nice ideas behind paravirt is that CONFIG_XEN=y can be included in a standard configuration and be no worse for native booting than as a Xen guest. The glibc feature that supports the vDSO "nosegneg" note is designed specifically to make this easy. You just have to flip one bit at boot time. This patch makes Xen flip the bit, so a CONFIG_XEN=y kernel on bare hardware does not make glibc use the less-optimized library builds.
