Nixpkgs: `texlive.combine` fails to build

[jul1u5]

Describe the bug
texlive.combine fails to build

To Reproduce

$ nix-shell -p 'texlive.combine { }'                                            
these derivations will be built:
  /nix/store/x19ks22ag712scj1jl0jp8vqwf2rcpr8-texlive-combined-2019.drv
building '/nix/store/x19ks22ag712scj1jl0jp8vqwf2rcpr8-texlive-combined-2019.drv'...
created 1 symlinks in user environment
/nix/store/bd3xj2p79zrqkz9xr8daq6752avvv90f-stdenv-linux/setup: line 1304: cd: ./share/texmf/web2c/: No such file or directory
builder for '/nix/store/x19ks22ag712scj1jl0jp8vqwf2rcpr8-texlive-combined-2019.drv' failed with exit code 1
error: build of '/nix/store/x19ks22ag712scj1jl0jp8vqwf2rcpr8-texlive-combined-2019.drv' failed

Additional context
The error is: cd: ./share/texmf/web2c/: No such file or directory. And I think it happens here:
