Another approach would be to ask kbuild for
this information so we do not expose various filenames to the
outer world.

Somthing like this:

diff --git a/Makefile b/Makefile
index c41035a..8f488c9 100644
--- a/Makefile
+++ b/Makefile
@@ -1528,6 +1523,12 @@ kernelrelease:
 kernelversion:
 	@echo $(KERNELVERSION)
 
+kernelarch:
+	@echo $(ARCH)
+
+kernelsubarch:
+	@echo $(SUBARCH)
+
 # Single targets
 # ---------------------------------------------------------------------------
 # Single targets are compatible with:

This is analogous to the way we ask for
kernelrelease and kernelversion these days.
