test-many-klibc: Always use GNU ld for riscv64, s390x, and sparc64
* LLD 13 doesn't implement linker relaxation for RISC-V, which makes
it fairly useless. Having made relaxation work, I don't want to go
back and make it conditional.
* LLD 13 doesn't seem to handle SPARC-specific relocations yet.
* Debian's build of LLD 13 doesn't seem to include IBM Z (s390x)
support.
So introduce a "mixed" toolchain of Clang + GNU ld, and test that
instead of pure LLVM for these architectures.
