Hi all.
I can't compile IceCat on ARM-Rawhide branch (it's an issue related to
GCC-11?) because of this error:
167:32.34

I don't know if it's caused by a compiler flag (-mfpu=neon) conflicts.
Likely, you should be using the distro flags. We have have armv7
devices that don't support NEON so we don't compile with them by
default and applications should use run time detected fast paths for
devices that support NEON.
