building on armhf root

[Enne2]

Hi, I'm trying to build ffmpeg with your script on a debian bullseye on pbp with an aarch64 kernel and an armhf root but I think that there are some aarch64 libraries hardcoded somehere.
I get the error:
/libavutil/aarch64/bswap.h:31:5: error: invalid 'asm': invalid operand for code 'w'
Is there a way to fix this or maybe I've to compile with an arm64 buildchain?
thanks in advance

i've not tried to build arm32 userland, sorry. i may have time to check this in the next few months as i update the scripts this spring.
