This is a re-commit of the commit da05b143a308 ("x86/boot: Don't add the
EFI stub to targets") after the tagged patch incorrectly reverted it.
To summarize: 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.
