[WIP] [Guidance Wanted] Fix arm binaries compilation

[jgabriel98]

Bug description

The build toolchain and ppa packages tells it supports armhf which on debian seems to be arm6 and arm7 (...don't ask me why). But when building for armhf (32bit arm), it was compiling armv7l binaries for armv6l, causing myst executable to crash with "fatal error illegal instruction".

This same problem/bug happened on this other project: https://github.com/goreleaser/goreleaser/issues/2721 So my solution was lightly inspired on it.

Results

Got it working on my raspbery pizero W, with both

• directly running ./myst binaries (dynamic and static compilation)
• generating .deb package and installing it

It was crosscompiled from a linux x86_64 machine.

---

Note

Currently this PR is incomplete and can only generate the

• armv6 binaries (see buildBinaryFor() and packageStandalone() changes)
• .deb package (see PackageLinuxDebianArmv6l() changes)
• static build binaries (see PackageLinuxArmv6l() changes)

It didn't know what more needed to be refactored, since i don´t know how what happens after artifacts gets uploaded to S3 bucket.

So any assistance is welcome. Also feel free to reach on discord, i'm on the mysterium-network channel! (user: #gaba3535)
