How to solve "Couldn't find a target code interpreter. Try with -fexternal-interpreter" error when building `.#static`?

[futu2]

I just have a plain project which using string-interpolate relies on TH. Run nix build .#static got the error below, while for my other non-TH projects build static work and output static linked executable.

nix build .#static

hi @futu2! This is a limitation in nixpkgs currently, see NixOS/nixpkgs#275304 for more information.
The PR NixOS/nixpkgs#383165 claims to implement a workaround, but I couldn't manage to get any of the combinations of pkgsStatic, pkgsMusl and bignum-native to execute splices.
So, we'll have to wait for the time being.
