[PATCH makedumpfile] Handle __mips64 as __mips64__ to avoid build failure

[HAGIO KAZUHITO(萩尾 一仁)]

From: Fabrice Fontaine <fontaine.fabrice at gmail.com>

Handle __mips64 as __mips64__ to avoid the following build failure:

makedumpfile.c: In function 'is_kvaddr':
makedumpfile.c:1613:39: error: 'KVBASE' undeclared (first use in this function)
   return (addr >= (unsigned long long)(KVBASE));
                                        ^~~~~~

Fixes:
  - http://autobuild.buildroot.org/results/94824fa8baa8edb99a5ca245e5561e0c4e430638
