OK. I see the real problem.
The rules to build spirv_info.c are incorrectly
to use $(LOCAL_PATH).
Basically speaking, $(LOCAL_PATH) can't be used
in the recipes[1] since it is always changing.
When the recipe rules are executed its value
is not you expected.
(using it in targets and prerequisites is OK)
The typical way to handle it is to use private variable:
$(intermediates)/spirv/spirv_info.c: PRIVATE_LOCAL_PATH := $(LOCAL_PATH)
Then use PRIVATE_LOCAL_PATH in the recpies.
But in this case, seems it can just be simplified to $^
(which means all the prerequisites)
$(intermediates)/spirv/spirv_info.c:
$(COMPILER_PATH)/spirv/spirv_info_c.py
$(COMPILER_PATH)/spirv/spirv.core.grammar.json
@mkdir -p $(dir $@)
$(hide) $(MESA_PYTHON2) $^ $@ || ($(RM) $@; false)
