libblastrampoline.so.5 not found

[JuhaHeiskala]

Hi,
I made a new binary package (QRupdate_ng_jll) for some QR/LU functions from Octave.

I get an error when "using QRupdate_ng_jll"
julia> using QRupdate_ng_jll ERROR: InitError: could not load library "/home/juha/.julia/artifacts/d9f2b00dc34fe490b6bf1eab76ef95160d0d1e7f/lib/libqrupdate.so" libblastrampoline.so.5: cannot open shared object file: No such file or directory
I have libblastrampoline.so in julia-1.7.1/lib/julia
and if I manually create libblastrampoline.so.5 link to point to libblastrampoline.so
then "using QRupdate_ng_jll" works

So why is the .5 added to libblastrampoline.so?
Something to do with libgfortran.5 that is used?

Just checked Julia 1.8.0 and it has the libblastrampoline.so.5 by default, so I guess this was an old issue.
