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.
