I am seeing the following build error for ARM with the
multi_v7_defconfig on our builders ...

  CC      drivers/firmware/qcom_scm-32.o

# first bad commit: [0c23125c509b41be51f0d5acb843b079a098a40c] kbuild: Update assembler calls to use proper flags and language target

Reverting this fixes it but I also needed to revert the following due to dependencies ...

Nathan Chancellor <nathan@xxxxxxxxxx>
    kbuild: Add KBUILD_CPPFLAGS to as-option invocation

Nathan Chancellor <nathan@xxxxxxxxxx>
    kbuild: Add CLANG_FLAGS to as-instr
