Add a paragraph about an optimization bug in SGI compilers which affects 

complex objects, and explain how to build so that Objects/complexobject.c
is compiled without optimization.

There is a bug in the SGI compiler's optimization that causes a
bus error in PyComplex_ImagAsDouble(); this has been reported to
be triggered when importing Numeric Python and may be caused at
other times. The work-around is to build Python, delete the
Objects/complexobject.o file, and then recompile without
optimization (use "make OPT=").
