Subject: [PATCH] libe-book: fix cross-compilation

What's been tested:

```
nix-build -I nixpkgs=channel:nixos-unstable -E 'let pkgs = import <nixpkgs> { }; in pkgs.callPackage ./pkgs/by-name/li/libe-book/package.nix { }'
```
```
nix-build -I nixpkgs=channel:nixos-unstable -E 'let pkgs = import <nixpkgs> { crossSystem = { config = "aarch64-unknown-linux-gnu"; }; }; in pkgs.callPackage ./pkgs/by-name/li/libe-book/package.nix { }'
```
```
nom-build -I nixpkgs=channel:nixos-unstable -E 'let pkgs = import <nixpkgs> { crossSystem = { config = "riscv64-linux"; }; }; in pkgs.callPackage ./pkgs/by-name/li/libe-book/package.nix { }'
```
