`USE_SYSTEM_CSL` - `libquadmath` loading

When using USE_SYSTEM_CSL=1, even if libquadmath is symlinked to the private lib/julia directory, the library is resolved to a system path:

julia> using Libdl
julia> foreach(println, Libdl.dllist())

libquadmath is a dependency of libgfortran.

I don't know if this is relevant (I'm not very familiar with julia loading mechanism, does it use DT_RPATH or DT_RUNPATH ?), but on my system (linux):

$ patchelf --print-rpath [USE_SYSTEM_CSL=1_build]/bin/../lib/julia/libgfortran.so.5

$ patchelf --print-rpath [official_julia_release]/bin/../lib/julia/libgfortran.so.5
$ORIGIN

Should libquadmath be explicitly loaded before libgfortran in CompilerSupportLibraries_jll ?
