    flatpak: Disable -Werror for gnome-online-accounts
    
    AX_COMPILER_FLAGS promotes all warnings to errors for non-release
    builds. While we have been working to reduce the number of warnings,
    most of them originate from the use of deprecated API and it will take
    us a bit longer to attain a 100% warning-free build.
