Subject: [PATCH] lib/vdso: use "grep -E" instead of "egrep"
Date:   Tue, 20 Sep 2022 19:06:33 +0200

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
	egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the vdso Makefile to use "grep -E" instead.
