Re: Dar binary doesn't run on Big Sur

I've published a modified Homebrew formula to install dar on Big Sur while this upx issue is sorted out. Admittedly this is my first ever attempt at a custom Homebrew formula. However the process is well documented, and brew has automated CI workflows to test and check formulas before you publish. 

Usage:
$ brew tap gonewest818/tap
$ brew install gonewest818/tap/dar
$ dar -h

On Catalina this formula grabs the bottle from the Releases area in my GitHub project.  On Big Sur this formula will download and builds from sources, because my tap has no precompiled bottle for Big Sur.

If you want to see the configuration, it’s here https://github.com/gonewest818/homebrew-tap
Please submit issues to that GitHub project if you find any issues with the results.

Hope this helps,
Neil

However, reading the documentation a little more closely it seems Homebrew has a policy that doesn’t permit options on core packages, because they can’t test all the permutations that would arise.  I’ll just run locally for now and presumably the upx project will sort out their issue sooner or later.
