MC and lld/ELF defaults were flipped in 2016. For Clang: CMake ENABLE_X86_RELAX_RELOCATIONS defaults to on in 2020. It makes sense for the TargetOptions default to be true now. R_X86_64_GOTPCRELX/R_X86_64_REX_GOTPCRELX require GNU ld newer than 2015-10 (subsumed by the current requirement of -fbinutils-version=). This should fix `rustc -Z plt=no` PIC relocatable files with GNU ld. (See https://github.com/rust-lang/rust/pull/106380)
