[Lldb-commits] [lldb] [lldb][tests] Fix passing pthread library to a linker for some API tests. (PR #93648)

[Vladimir Vereschaka via lldb-commits]

https://github.com/vvereschaka created https://github.com/llvm/llvm-project/pull/93648

Specify ENABLE_THREADS := YES within test's Makefile instead passing -lpthread throuhg the compiler's CFLAGS options.

Updated the following tests:

* lldb/test/API/commands/register/register/aarch64_sme_z_registers/za_dynamic_resize/Makefile
* lldb/test/API/commands/register/register/aarch64_sve_registers/rw_access_dynamic_resize/Makefile
* lldb/test/API/functionalities/process_save_core_minidump/Makefile
* lldb/test/API/tools/lldb-dap/threads/Makefile

Fixes the following compiler/linker messages and error:

```
clang: warning: -lpthread: 'linker' input unused [-Wunused-command-line-argument]
...
ld.lld: error: undefined symbol: pthread_create
...
```

Depends on #93639
