    Cygwin: Ensure PSAPI_VERSION is 1 when building ldd
    
    The default PSAPI_VERSION is controlled by WIN32_WINNT, which we set to
    0x0a00 when building ldd, which gets PSAPI_VERSION=2.
    
    This causes K32GetModuleFileNameEx to be used for GetModuleFileNameEx,
    which isn't available on Windows Vista.
    
    Define PSAPI_VERSION as 1 for the built executable to work on Windows
    Vista.
