However,\ncpp_flags also includes $(PLATFORM_CPPFLAGS), which carries\narchitecture-specific flags such as -march=armv8-a+crc set by\narch/arm/Makefile for CONFIG_ARM64_CRC32=y targets. These flags are\nappropriate for cross-compiled object files but cause the host CPP\ninvocation to fail on x86 build machines:\n\n cc1: error: bad value ('armv8-a+crc') for '-march=' switch\n\nKBUILD_CPPFLAGS already accumulates the user-supplied KCPPFLAGS via\n\"KBUILD_CPPFLAGS += $(KCPPFLAGS)\", providing the behaviour 2956a84\nintended without pulling in target architecture flags.
