Allow jlibtool to compile and link on mingw.

The notable bits here are:
- mingw doesn't have fork() or waitpid()
- mkdir() doesn't take the umask parameter
- The MSVCRT runtime is 'safe' and reparses anything that isn't separated with
  a double-quote; so add quotes around our escaped statement to run.
