6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Segall <bsegall@xxxxxxxxxx>
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.
Fixes: cb8bda8ad443 ("x86/boot/compressed: Rename efi_thunk_64.S to efi-mixed.S")
