Summary: Include/pyport.h: Bad LONG_BIT assumption on non-glibc sys

Initial Comment:
While attempting to compile on Solaris 8 64-bit or HPUX 
64-bit, Python 2.3.4 has an "error" because LONG_BIT is 
not defined properly.  This error is incorrect on non-glibc 
systems, and Python compiles fine with it disabled.  
Here's the incorrect assumption:

#if LONG_BIT != 8 * SIZEOF_LONG
/* 04-Oct-2000 LONG_BIT is apparently (mis)defined as 
64 on some recent
 * 32-bit platforms using gcc.  We try to catch that 
here at compile-time
 * rather than waiting for integer multiplication to trigger 
bogus
 * overflows.
 */
#error "LONG_BIT definition appears wrong for platform 
(bad gcc/glibc config?)."
#endif

This should include something to limit it to only glibc 
systems.
