linker: Fix weak lang item linking with combination windows-gnu + LLD + LTO In https://github.com/rust-lang/rust/pull/100404 this logic was originally disabled for MSVC due to issues with LTO, but the same issues appear on windows-gnu with LLD because that LLD uses the same underlying logic as MSVC LLD, just with re-syntaxed command line options. So this PR just disables it for LTO builds in general.
