6.9-stable review patch. If anyone has any objections, please let me know.

From: Benjamin Segall bsegall@google.com
commit b2747f108b8034271fd5289bd8f3a7003e0775a3 upstream.
This is a re-commit of
da05b143a308 ("x86/boot: Don't add the EFI stub to targets")
after the tagged patch incorrectly reverted it.
vmlinux-objs-y is added to targets, with an assumption that they are all relative to $(obj); adding a $(objtree)/drivers/... path causes the build to incorrectly create a useless arch/x86/boot/compressed/drivers/... directory tree.
Fix this just by using a different make variable for the EFI stub.
