[PATCH] fix for MIPS system headers needing _MIPS_SZ{INT,LONG,PTR}

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

System headers (at least glibc's ones) define and use __WORDSIZE
which, on most archs, is defined depending on __LP64 or __ILP32.
But on MIPS, __WORDISZE is defined depending on the value of the
builtin macro _MIPS_SZPTR.

So, add the predefine for _MIPS_SZPTR on MIPS.
