[Tarantool-patches] [PATCH] build: add missing module for jit.dump on ARM64

[Sergey Ostanevich]

Thanks for the patch,

LGTM.

As for the plurality of dis modules - can we make decision at load time,
same as in dis_x64? So we’d introduce a set of dis_<target>.lua in Tarantool
sources that will make a check if target is valid and load the luajit one.
Definitely - not in this patch.
