with gcc-9, armv5 is now a deprecated keyword, resulting the build in:

So, I propose to use armv7, that is the bare minimum required for Debian...
This might become RC when gcc-9 defaults, but I think the current binary is not really optimized for armhf, so I prefer to
have an higher severity.
Of course, no strange point from my side, so feel free to downgrade as you wish!
thanks
