    Miscellaneous Win32 related build fixes
    
    - Initialize libtool, thus the 'host' variable is properly initialized
      in the check for a Win32 build.
    - Build libcamelews-priv.la as a shared library in Win32, to avoid symbol
      duplication.
    - Store shared libraries into 'bin' folder in Win32.
