SRCARCH is always equal ARCH. There are no rules when to use one or another and architectures may forget to set one of them up. No need for a second variable meaning the same and confusing people. Remove it completely. Self-correction [after some debug]: SRCARCH was different in one place: zdtm Makefile by some unintentional mistake: > ifeq ($(ARCH),arm64) > ARCH ?= aarch64 > SRCARCH ?= aarch64 > endif That meant to be "ARCH := aarch64" because "?=" would never work inside that ifeq. Fix up this part of mess too. Signed-off-by: Dmitry Safonov <dima@arista.com> Signed-off-by: Andrei Vagin <avagin@gmail.com>
