Clang can assemble these files just fine; this is a relic from the top

--gcc-toolchain, or -Qunused-arguments flags either with this change, so
remove those too.
To test building:
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \
CROSS_COMPILE_COMPAT=arm-linux-gnueabi- make LLVM=1 LLVM_IAS=1 \
defconfig arch/arm64/kernel/vdso32/
