[gnome-continuous-yocto/gnomeostree-3.28-rocko: 5452/8267] ncurses_6.0: Improve reproducibility

[Emmanuele Bassi <ebassi src gnome org>]

    ncurses_6.0: Improve reproducibility
    
    Build static libraries without the binutils "ar" -U option.
    This option deliberately breaks deterministic mode.
    The option seems to be a relic from 2015, intended as a workaround
    for some unspecified build problems.

+"configure" enforces -U for ar flags, breaking deterministic builds.
+The flag was added to fix some vaguely specified "recent POSIX binutil
+build problems" in 2015.
