Do not create clang-db when cross-compiling w/mingw 

This breaks windows builds, since apparently build(bld) is
evaluated twice (once to write compile_commands.json and once
to compile), even though `obj` is reset.

eg. in libs/pbd/wscript

```
if bld.env['build_target'] == 'mingw':
  obj.source += [ 'windows_special_dirs.cc' ]
```

results in

[  65/1159] Compiling libs/pbd/windows_special_dirs.cc
[  69/1159] Compiling libs/pbd/windows_special_dirs.cc

which then produces an error when linking:
```
/usr/bin/x86_64-w64-mingw32-ld: libs/pbd/windows_special_dirs.cc.2.o:libs/pbd/windows_special_dirs.cc:28: multiple definition of `PBD::get_win_special_folder_path[abi:cxx11](int)'; libs/pbd/windows_special_dirs.cc.2.o:libs/pbd/windows_special_dirs.cc:28: first defined here
```
