Due to Cargo #8875, it is not currently possible
to link to so-called "fat" libraries. However, in
WL ~v12.3 and later, WSTP is distributed as a fat binary
containing native code for for both x86_64 and arm64 targets.
To work around this incompatibility, the macOS lipo
command is used to generate a "thin" library, which cargo
is able to successfully link against.
