Regardless of what this library does, if you need to preload it for
Guix-built applications, then this library should also be built from
Guix (otherwise you end up with several libcs, etc. in the same process,
which is never a good thing.)

So I’d recommend packaging this library and then you can hopefully
preload at will.  :-)
