   1 Build objects twice for shared and static libraries
   2
   3 The existing Makefile causes problems on MIPS because the same object
   4 files (not compiled with -fPIC) are used in static and shared libraries.
   5 MIPS will refuce to link non-pic objects in shared libraries.
   6 We fix this problems by creating a new rule for the shared library
   7 and build the shared objects as *.sho instead of *.o.
   8 Then, we use these objects to create the shared library.
