Ugh.
A wise man once said: "All problems in computer science can be solved
with another level of indirection".
Just do it like this:
CLANG_TARGET_FLAGS_arm = arm-linux-gnueabi
CLANG_TARGET_FLAGS_hexagon = hexagon-linux-gnu
..
CLANG_TARGET_FLAGS = $(CLANG_TARGET_FLAGS_$(ARCH))
Which is a lot denser and simpler.
And then the only if-statement can be something along the lines of
ifeq ($(CLANG_TARGET_FLAGS),)
$(error Specify clang target flags)
else
CLANG_FLAGS += --target=$(CLANG_TARGET_FLAGS)
endif
Plus add *random handwaving* about all the details for CROSS_COMPILE
and friends.
