Interesting, when I run configure having defined AS to be GNU AS :

AS=/usr/bin/aarch64-linux-gnu-as ./configure --host=aarch64-linux-gnu
--cross-prefix=aarch64-linux-gnu- --prefix=/opt/ffbuild
--enable-static --disable-lavf --disable-opencl


The make fails with a different error:

/usr/bin/aarch64-linux-gnu-as -I. -I. -c -DSTACK_ALIGNMENT=16 -o
common/aarch64/bitstream-a-8.o common/aarch64/bitstream-a.S
-DHIGH_BIT_DEPTH=0 -DBIT_DEPTH=8
/usr/bin/aarch64-linux-gnu-as: invalid option -- 'S'
make: *** [Makefile:306: common/aarch64/bitstream-a-8.o] Error 1


gas in not liking the -D options, and is failing on the S of -DSTACK_ALIGNMENT.


Maybe I'm using a version of gas which is too old?
I'm using the gas which comes with Ubuntu 20.04.3 LTS.
