tcc -vv/--print-search-dirs: print more info

tests/Makefile:
- print-search-dirs when 'hello' fails
- split off hello-run

win32/include/_mingw.h:
- fix for compatibility with mingw headers
  (While our headers in win32 are from mingw-64 and don't have
  the problem)

tiny_libmaker:
- don't use "dangerous" mktemp
