While working on hotspot/src/os/linux/vm/os_linux.cpp to add new architectures for Zero, I noticed that the identifier strings for PowerPC 64 and PowerPC 64 LE are swapped:

#if defined(VM_LITTLE_ENDIAN)
    {EM_PPC64, EM_PPC64, ELFCLASS64, ELFDATA2LSB, (char*)"Power PC 64"},
#else
    {EM_PPC64, EM_PPC64, ELFCLASS64, ELFDATA2MSB, (char*)"Power PC 64 LE"},
#endif

The upper entry should have the string "PowerPC 64 LE" and the lower one "PowerPC 64", not vice versa.
