Recently, Solaris bootstrap got broken because Solaris uses a non-standard mangling of `std::tm` and a few others. This was fixed with a hack in PR #100724. The Solaris ABI requires mangling `std::tm` as `tm` and similarly for `std::div_t`, `std::ldiv_t`, and `std::lconv`, which is what this patch implements. The hack needs to stay in place to allow building with older versions of `clang`. Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11` (2-stage builds with both `clang-19` and `gcc-14` as build compiler), and `x86_64-pc-linux-gnu`.
