After upgrading to macOS Catalina, my Unity 2018.3 fails to compile for Android using il2cpp.
The error seems to happen during the linking process.
Here's the output:

Looks like in the NDK there is no linker ld-bfd for darwin-x86_64 :(
Do you have any idea on how to fix?
I've found a (really bad) workaround, that... works.
Navigate to your NDK folder, then:
cd toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/aarch64-linux-android/bin
Now, copy the gold linker as bfd:
cp ld.gold ld.bfd
Not sure if it has any side effect, but, well... it compiles!
