Make some structs non-empty
GCC shows warnings like this when compiling libraries or programs linking to
libunwind:
```
/buildworker/worker/package_linuxaarch64/build/usr/include/libunwind-aarch64.h:60:9: warning: empty struct has size 0 in C, size 1 in C++ [-Wc++-compat]
typedef struct
^~~~~~
/buildworker/worker/package_linuxaarch64/build/usr/include/libunwind-aarch64.h:169:16: warning: empty struct has size 0 in C, size 1 in C++ [-Wc++-compat]
typedef struct unw_tdep_save_loc
^~~~~~~~~~~~~~~~~
```
The pattern of using a dummy field is already used in other platforms.
