This is not an internal name, but was derived from an Apple header file.  Compare
the definition of bfd_mach_o_cpu_type with:

...
#define CPU_TYPE_MC98000        ((cpu_type_t) 10)
#define CPU_TYPE_HPPA           ((cpu_type_t) 11)
#define CPU_TYPE_ARM            ((cpu_type_t) 12)
#define CPU_TYPE_ARM64          (CPU_TYPE_ARM | CPU_ARCH_ABI64)
#define CPU_TYPE_MC88000        ((cpu_type_t) 13)
#define CPU_TYPE_SPARC          ((cpu_type_t) 14)
#define CPU_TYPE_I860           ((cpu_type_t) 15)
/* skip CPU_TYPE_ALPHA          ((cpu_type_t) 16)       */
/* skip                         ((cpu_type_t) 17)       */
#define CPU_TYPE_POWERPC                ((cpu_type_t) 18)
...

I added BFD_MACH_O_ prefix as a namespace.
