`R_X86_64_GOTTPOFF` linking error in x32 architecture.

(this is a continuation of https://github.com/ziglang/zig/issues/25374)

This issue exists in LLVM 18(?) to 21 and there isn't any resolve yet. hopefully this gets fixed.

The Error:

```

Start by reproducing the x32 build with the provided CMake flags and lld link command. Inspect the reported Relocations.cpp.o diagnostics for R_X86_64_GOTTPOFF and compare the failing link behavior across the affected LLVM versions. Done means the x32 LLVM build completes without this linker error, with an appropriate regression test if the relevant test location is identified.
