OK, so this is the command line GCC uses to invoke the assembler when
building aes-ce-cipher.o

 /usr/local/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/../lib/gcc/aarch64-linux-gnu/4.9.1/../../../../aarch64-linux-gnu/bin/as
-v -I /home/ard/linux-2.6/arch/arm64/include -I
arch/arm64/include/generated/uapi -I arch/arm64/include/generated -I
/home/ard/linux-2.6/include -I include -I
/home/ard/linux-2.6/arch/arm64/include/uapi -I
arch/arm64/include/generated/uapi -I /home/ard/linux-2.6/include/uapi
-I include/generated/uapi -I /home/ard/linux-2.6/arch/arm64/crypto -I
arch/arm64/crypto -EL -march=armv8-a+crypto -mabi=lp64 -o
arch/arm64/crypto/aes-ce-cipher.o /tmp/ccqUB3dr.s

So in my case, it correctly relays the -march option to GAS, and it
builds fine. Note that I am not using a bare metal compiler, but I
don't think that that should make a difference.

GCC -v output:

Anyone care to try the same with the non-working toolchain?
