New gcc changed the way it exposes armhf build flags.
"the architecture now has to include the cpu features, see the man page, arM options"

example of build failure:
https://launchpad.net/ubuntu/+source/ffmpeg/7:4.4-6ubuntu1/+build/22070856

Note: this syntax was introduced in GCC 8 https://gcc.gnu.org/gcc-8/changes.html
