Include some notes on compiling with armv6.

| Note that this does not work with armv6 (found e.g. in Raspberry Pi 1 and Zero). Previously, you could use the linker in https://github.com/raspberrypi/tools, but this is now too old and will give an error when compiling Librespot (since `3e85d77bfb3520e16c35bb7db3912c76e8cc90d7`).

I compile librespot for armv6 using the official raspi tools no problem. But I don't use cargo cross. I suggest just stating your method doesn't work for pi 1 and zero.

I'm also not using cargo cross. After commit 3e85d77 I get an error from the rpi tools linker saying it found dwarf version 6, but only supports versions 1-4. Maybe I'm using a newer version of Rust (I'm on 1.82.0)?

I'll update and see what I get. Does this happen even when compiling with the release profile?

@oyv friendly nudge - did you get around to testing what @kingosticks asked?

So whats the current state of things on this?
- @kingosticks did you also run into this problem after updating your setup?
- @oyv did you check what @kingosticks asked?

Maybe I'm wrong, but shouldn't line 118 must be
rustup target add armv7-unknown-linux-gnueabihf ? So with "hf" at the end?
When I try this (to compile it for TinyCore) I get:
warning: openssl-sys@0.9.109: Could not find directory of OpenSSL installation,
and this -sys crate cannot proceed without this knowledge. If OpenSSL is installed
and this crate had trouble finding it, you can set the OPENSSL_DIR environment
variable for the compilation process. See stderr section below for further information.
error: failed to run custom build command for openssl-sys v0.9.109
