WINGs shared library generation

This patch modifies the linking of the WINGs libraries
to create a shared library. wmaker used to do this, but
it was dropped around wmaker-0.90/0.91.
The shared .so library is needed when compiling and running
the wdm display manager and any other programs which link
to libWINGs.
