The flag does indeed exist. However, it is not intended for regular 
end-users, but rather to help developers when fiddling around with 
auto-detection/cross-compilation setups, etc. In normal use, the 
GCC-style linker driver to use should be auto-detected from the CC 
environment variable. The problem here was just that lit didn't forward 
it to the test processes.
