6## GCC collect2 passes several LTO related options to the linker even if -flto is not used.
7## We need to ignore them. Note that the lto-wrapper path can be relative.

19## Clang LTO passes several options to the linker, which are intended to be consumed by
20## LLVMgold.so. We need to ignore them.

23## Other -plugin-opt=- prefixed options are passed through to cl::ParseCommandLineOptions.
