This lets rustc users tweak whether the linker should relax ELF relocations, namely whether it should emit R_X86_64_GOTPCRELX relocations instead of R_X86_64_GOTPCREL, as the former is allowed by the ABI to be further optimised. The default value is whatever the target defines. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
