Missing ARM64 support in `deploy_init`

[calladoum-elastic]

Description

Hi @horsicq

When building on non-x86, deploy_init will default to x86.

https://github.com/horsicq/build_tools/blob/7bc9c9ecbef38e9a54fc8c59a465f0a0b33b5a3b/cmake/deploy.cmake#L2-L25

Resulting in logs like this:

Strangely enough, this does not prevent the build of dielib on arm64

I'm dropping this issue as a reminder, I should be able to PR it later (if you don't get to it first)
