Subject: [PATCH] QtWebKit/Windows: Use jom instead of nmake, if present

Detect if jom.exe is in the PATH. If so, use Jom instead of
nmake to compile, since Jom supports building on several cores.

Had to roll out own find_exe function, since File::Which doesn't
seem to be installed by default on certain Linux systems.
