[llvm] tblgen: fix dependency for gnu-ld (PR #161951)

[via llvm-commits]

https://github.com/aokblast created https://github.com/llvm/llvm-project/pull/161951

In gnu-ld, all symbols reference to an archive file should be placed before the archive itself. For example, libLLVMTableGen references the symbols in libLLVMSupport, and the libLLVMTableGen should be placed before it. Therefore, we reorder the archive orders.
