llvm dev - Aug 2010 - [LLVMdev] Checking llvm-config status code

Hm, it turns out that only GNU make has $(error...). Does anyone know
how we can simulate it in generic make?

For GNU it's easy but ugly:
  LlvmConfigResult := $(shell $(LLVM_CONFIG) --libs
$(LINK_COMPONENTS) || echo Error)
  ifeq ($(LlvmConfigResult),Error)
  $(error llvm-config failed)
  endif
  LLVMLibsOptions += $(LlvmConfigResult)

$(error) is implemented since 3.78. LLVM requires 3.79.

Ah, so LLVM already requires GNU make. Fine, than I'll submit the
patch in the evening.
