Hi panxiaohe,

Because accepting -V as an alternative to the -v option is an x86 specific
feature.  In particular -V is supported by the x86 assembler because the same
option is supported by the old SVR4 assembler.  Ie this is a backwards
compatibility feature.

The AArch64 assembler does not need to be backwards compatible with earlier
assemblers (there are none) and so it does not support the -V option.

Note that both assemblers do support -v and --version.
