Iâd mostly like to be just able to do something along the lines of
`dlopen("X")` to load the appropriate libX shared library that exists in the
system for arbitrary X. When `libm.so` was a (link to a) proper shared library
you could simply do `dlopen("lib" "X" ".so")` (or some sort of runtime string
stitching), but now that is not possible anymore for "X" = "m". 

Writing this I realised there also are a few other libraries that do the ld
script thing, so it might be simply me approaching library search the wrong
way, which sounds about right.
