We're getting the following error while building a large binary on macOS with
code coverage instrumentation:

ld: 32-bit RIP relative reference out of range (2845947809 max is +/-4GB): from

clang: error: linker command failed with exit code 1 (use -v to see invocation)


Is there anything we can do to avoid that issue? As I understand, __llvm_covmap
referenced are RIP relative, but is it really necessary? The same binary links
successfully on Linux, even though __llvm_covmap section is even larger over
there.
