Linking failed with -Clinker-plugin-lto

note: error: unsupported linker arg: -plugin-opt

This prevents cross-lang lto from being used

Not much we can do here besides filtering out the unsupported linker arg unless zig cc adds support?

[NobodyXu]

Yeah filtering is good enough, rustc use linker-plugin-lto to ask linker to load llvm gold plugins to do cross lang LTO, since zig-cc is already LLVM it doesn't need it, just ignoring it would be fine
