+Build objects twice for shared and static libraries
+
+The existing Makefile causes problems on MIPS because the same object
+files (not compiled with -fPIC) are used in static and shared libraries.
+MIPS will refuce to link non-pic objects in shared libraries.
+We fix this problems by creating a new rule for the shared library
+and build the shared objects as *.sho instead of *.o.
+Then, we use these objects to create the shared library.
