Hi all,

I recently gave LLD a try and it definitely works fine. However one cannot
build it together with LLVM_LINK_LLVM_DYLIB:
ELF/Driver.cpp and ELF/DriverUtils.cpp pull in llvm/Support/CommandLine.h
which defines the command line options so these global variables end up in
libLLVM-4.0svn.so via liblldELF.
If this shared library is then linked into bin/lld or bin/opt one gets
errors because of "Option '...' registered more than once" as they are also
present in the binaries themselves.

Is it possible to keep the global variables for command line options out of
