Revision 342

Compile fixes from linuxBIOS hopefully it works for everyone again.

crt0.base
     - SMP compile fixes
     - No longer unconditionally include cpu/p5/start32.inc
         (it's been renamed  cpu/i386/entry16.inc)
ldscript.base
     - Simplfied, and moved some content into reset16.lds and entry16.lds
stddef.h
     - Use C style comments for #endif /* I386_STDDEF_H */
pirq_routing.h
     - The define is HAVE_PIRQ_TABLE not HAVE_PIRQ_ROUTING_TABLE
mtrr.c
     - Remove the need for defining INTEL_PPRO_MTRR
mainboard/xxx/Config
     - start32.inc is no longer automatically included include
       entry16.inc and reset16.inc where appropriate
       In particular if we are using a docipl we don't want
       reset16.inc or reset16.lds
tyan/guiness/mptable.c
     - Removed spurious define USE_ALL_CPUS
northbridge/intel/440gx/
     - Updated to compile with the factored generic memory code.
nortsouthbridge/sis/xxx/
     - Remove includes of northsouthbridge/sis/630/param.h did I add them?
       The file is gone now so including it is just bad...
NLBConfig.py
      - Allow relative filename arguments
      - Add directive ldscript to add an include file into
        our linker script
      - Fixed docipl to use strings when calling set_option
      - Allow target the target directive to use relative paths
      - Add extra dependencies to ldscript.lds
