--------------------------------

On my aarch64 big endian machine, the perf annotate does not work.

 # perf annotate
  Percent |      Source code & Disassembly of [kernel.kallsyms] for cycles (253 samples, percent: local period)
 --------------------------------------------------------------------------------------------------------------
  Percent |      Source code & Disassembly of [kernel.kallsyms] for cycles (1 samples, percent: local period)
 ------------------------------------------------------------------------------------------------------------
  Percent |      Source code & Disassembly of [kernel.kallsyms] for cycles (47 samples, percent: local period)
 -------------------------------------------------------------------------------------------------------------
 ...

This is because the arch_find() function uses the normalized architecture
name provided by normalize_arch(), and my machine's architecture name
aarch64_be is not normalized to arm64.  Like other architectures such as
arm and powerpc, we can fuzzy match the architecture names associated with
aarch64.* and normalize them.

It seems that there is also arm64_be architecture name, which we also
normalize to arm64.
