Install a libglaze-32.so library along with a glaze-32.pc file.

Install a libglaze-32.so library along with a glaze-32.pc file.

This is the helper library that Glaze-using libraries can link against.
Previously, it was only compiled in a native version (named libglaze.so).
Now, we compile a 64-bit version named libglaze.so and a 32-bit version
named libglaze-32.so.
