ARM64 / aarch64 Linux support

[nth10sd]

Is ARM64 / aarch64 Linux (e.g. on Ubuntu) going to be supported anytime soon - or am I missing documentation somewhere?

[markcmiller86]

@nth10sd We do make binaries availabe for Ubuntu but not for ARM processors.

You are not missing any documentation.

However, we do describe our supported platforms as well as the factors that impact those choices in our documentation.

I hit a compile error with 3.3.1 tarball:

@markcmiller86 A guess is that the architecture is not being detected so it "falls back" to x86_64 32-bit.
