Simon Pilgrim ([1]) and Anton reported that the following warning will
appear when building clang compiler:
```
In file included from .../llvm-project/llvm/lib/Target/BPF/BPFASpaceCastSimplifyPass.cpp:9: .../llvm-project/llvm/lib/Target/BPF/BPF.h:25:20: warning: ‘llvm::BPF_TRAP’ defined but not used [-Wunused-variable]
25 | static const char *BPF_TRAP = "__bpf_trap";
| ^~~~~~~~
...
In file included from .../llvm-project/llvm/lib/Target/BPF/MCTargetDesc/BPFInstPrinter.cpp:14:
.../llvm-project/llvm/lib/Target/BPF/BPF.h:25:20: warning: ‘llvm::BPF_TRAP’ defined but not used [-Wunused-variable]
25 | static const char *BPF_TRAP = "__bpf_trap";
| ^~~~~~~~
...
```
Instead of using static const variable, use macro to silence warnings.
