Needless to say, the fonts are available in Emacs regardless.  It's
only the font selection dialog that may be unavailable, but font
settings via, e.g., set-frame-font, set-fontset-font, etc., work
regardless.  IOW, this is just a GUI feature, which depends on the
toolkit's abilities; it doesn't affect what fonts Emacs can use.
