In the land of the blind the one-eyed man is king 🙂 Po Lu knows more
about this stuff than I do.

I verified Bug#37786 and Bug#30874 on a Xft + HarfBuzz build, it works
as intended. This is with libXft 2.3.6.

And I noticed that Po Lu has already done the work to only exclude
colour fonts on older releases of libXft:

    commit cc30758eed9488aed4149adbf7a285622c3ec446

        Enable support for color fonts in recent releases of Xft

        * etc/PROBLEMS (Some fonts are detected..): Document that Xft
        2.3.6 should have resolved this issue.

        * src/ftfont.c (ftfont_spec_pattern, ftfont_list): Disable
        inhibition of color fonts on Xft 2.3.6 and subsequent versions.

Iʼm neutral on whether we need to warn in configure for older versions
of libXft. On the one hand theyʼre buggy with colour fonts, on the
other hand we ignore those colour fonts anyway.
