Or update to a pre release version of rustc, like libvips did ;-}

Classic example of rust as a ... suboptimal choice for an
implementation language (or at least the rustc project as a disaster
choice for a compiler provider).

Maybe instead we should just downgrade to 1.53 and create a rule to not
update rust before a firefox release that requires a new version is in
pkgsrc (or in preparation for that, to avoid chicken vs. egg problems).
