* NXFindBestFatArch() is passed a cputype and cpusubtype and a set of
* fat_arch structs and selects the best one that matches (if any) and returns
* a pointer to that fat_arch struct (or NULL). The fat_arch structs must be
* in the host byte order and correct such that the fat_archs really points to
* enough memory for nfat_arch structs. It is possible that this routine could
* fail if new cputypes or cpusubtypes are added and an old version of this
* routine is used. But if there is an exact match between the cputype and
* cpusubtype and one of the fat_arch structs this routine will always succeed.
