Local Catalyst wheel build is broken on macOS

On my system (macOS 14 arm64), I can no longer build working wheels from a local repository. This is present on both v0.10 and v0.9. Besides changes in the Catalyst package, it could also be due to a change in build environment (OS or package updates).

The problem is down to the unique library ID of the custom_calls library as seen below (first line of a library is always itself):

otool -L PennyLane_Catalyst-0.9.0/catalyst/utils/libcustom_calls.so 
PennyLane_Catalyst-0.9.0/catalyst/utils/libcustom_calls.so (architecture x86_64):
        build/lib.macosx-10.9-universal2-cpython-311/catalyst/utils/libcustom_calls.so (compatibility version 0.0.0, current version 0.0.0)
        /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1800.101.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1351.0.0)
PennyLane_Catalyst-0.9.0/catalyst/utils/libcustom_calls.so (architecture arm64):
        build/lib.macosx-10.9-universal2-cpython-311/catalyst/utils/libcustom_calls.so (compatibility version 0.0.0, current version 0.0.0)
        /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1800.101.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1351.0.0)

while the library is originally generated with the correct identifier (@rpath/libcustom_calls.so), when packaged into the wheel the identifier changes to build/lib.macosx-10.9-universal2-cpython-311/catalyst/utils/libcustom_calls.so which will cause a dynamic linker error when loading the custom calls library during execution.

I briefly tested to see if delocate would fix the wheel, but it doesn't. Wheels on the CI seem as of yet unaffected by this.

Reproduce the local wheel build on macOS 14 arm64 and inspect catalyst/utils/libcustom_calls.so with otool -L. Compare the original @rpath/libcustom_calls.so identifier with the packaged wheel's build/... identifier, and check whether delocate changes the result. Done means locally built wheels retain a loadable library identifier and custom calls load during execution.
