There is an updated pull request by subnut against master on the void-packages repository

https://github.com/subnut/void-packages mozjs91-91.5.0
https://github.com/void-linux/void-packages/pull/36241

New package: mozjs91-91.7.1
<!-- Uncomment relevant sections and delete options which are not applicable -->
#### Current state -
these i686 tests are failing (`js/src/jit-test/tests/basic/bug653153.js`) -
```js
// This is the boundary in practice.
assertEq(parseInt(1e21 - 65537) > 1e20, true);
assertEq(parseInt(1e21 - 65536), 1);
assertEq(parseInt(1e21 + 65536), 1);
 ```

That's because `parseInt(1e21 - 65537)` returns `1` instead of the correct `999999999999999900000`  
And that's because `(1e21-65537).toString()` returns `"1e+21"` instead of the correct `"999999999999999900000"`
