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

   CC      drivers/firmware/qcom_scm-32.o
/tmp/cc9gP1cd.s: Assembler messages:

# 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@...nel.org>
     kbuild: Add KBUILD_CPPFLAGS to as-option invocation

Nathan Chancellor <nathan@...nel.org>
     kbuild: Add CLANG_FLAGS to as-instr
