Build Failed in old MacOS version

[niu541412]

I have an outdated Mac Pro 5,1, but it is still capable of installing most Homebrew formulas by building from source.
The last officially supported MacOS version is 10.13 High Sierra. However, difftastic cannot be installed without code modification.
The following is the error log:

 error: failed to run custom build command for `libmimalloc-sys v0.1.24`

It appears that the issue is caused by the outdated mimalloc which is involved in libmimalloc-sys. There is a discussion regarding this matter.
This bug has been fixed since the upstream of https://github.com/microsoft/mimalloc/releases/tag/v1.7.6, and this version has been adopted since https://github.com/purpleprotocol/mimalloc_rust/releases/tag/v0.1.29.
The latest difftastic is using 0.1.24, which is still behind them.
