[Buildroot] "PATCH": hack to be able to build Rust targetting MIPS

[Alex Corcoles <alex@corcoles.net>]

Hi guys,

Just managed to get everything working. I've documented the whole process
at:

https://github.com/alexpdp7/retrofw2-rust

The problems are:

1) Rust updated their mips targets to mips32r2, while the kind of devices
I'm using are plain non-r1 mips32. I created a patch for buildroot that
patches Rust (on top of a patch I found that bumps it to Rust 1.40.0) to
use the proper instruction set. I've opened a bug to see if they change the
target or add a new one at:

https://github.com/rust-lang/rust/issues/68865

2) buildroot doesn't support building Rust for uclibc, I hardcoded that. It
would be nice to write a proper solution to this, but I'm not familiar
enough with buildroot. Does anyone know where I could request that?

3) I had some issues with sdl-mixer, which I fixed by pulling RetroFW's
sdl-mixer. This is even more terrible, but I have even less idea about how
to fix it.

Cheers,

?lex
