Does V8 have any plan on it,  by enabling a 64-bit version of mksnapshot 
that can produce 32-bit arm code?

i found Flutter/Dart has same problem, and fix it already,  see E 
<https://github.com/dart-lang/sdk/issues/36839>nable gen_snapshot to be 
compiled for X64 host and ARM target (SIMARM_X64 build) 
<https://github.com/dart-lang/sdk/issues/36839> .
