[PATCH] lib/vdso: use "grep -E" instead of "egrep"

[PATCH] lib/vdso: use "grep -E" instead of "egrep"

[Greg Kroah-Hartman]

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.
