Cannot code sign on Big Sur MacOS

[JonathanLoungani]

Describe the bug

When following the BeeWare tutorial on a Big Sur MacOS (x86_64), the briefcase build command is unable to code sign.

Steps to reproduce

1. Follow the steps in the BeeWare tutorial until Tutorial 3 – Packaging for distribution.
2. Run briefcase create
3. Run briefcase build
4. Observe that the briefcase build command fails with the following error:

Unable to code sign /Users/jonathanloungani/dev/beeware/beeware-tutorial/helloworld/build/helloworld/macos/app/Hello World.app.

Notably, the command

codesign '/Users/jonathanloungani/dev/beeware/beeware-tutorial/helloworld/build/helloworld/macos/app/Hello World.app' --sign - --force --entitlements /Users/jonathanloungani/dev/beeware/beeware-tutorial/helloworld/build/helloworld/macos/app/Entitlements.plist

Produces the following result:

/Library/Developer/CommandLineTools/usr/bin/codesign_allocate: fatal error: file not in an order that can be processed (link edit information does not fill the __LINKEDIT segment): /Users/jonathanloungani/dev/beeware/beeware-tutorial/helloworld/build/helloworld/macos/app/Hello World.app/Contents/MacOS/Hello World (for architecture x86_64)
/Users/jonathanloungani/dev/beeware/beeware-tutorial/helloworld/build/helloworld/macos/app/Hello World.app: the codesign_allocate helper tool cannot be found or used

Expected behavior

The ad-hoc signing should complete without issue.
