At the moment the solana target's std implementation has std::backtrace and std::error::Error::backtrace commented out. Crates are beginning to expect these functions to exist: anyhow in particular does not compile with the solana rust toolchain when targeting bpf unless one disables its support for std, which makes it much less pleasant to use.

Add the backtrace API back but with stubs that do nothing, return empty traces, etc. Verify that anyhow builds against bpf targets with it.

Hey, I was thinking about building this toolchain using nix. In order to be able to do that I need flags which need to be passed over to ./configure so that the Nix build can work its magic by passing the right stuff to the resulting Makefile.

A reproducible build of the Solana ecosystem sounds like a great way to make life easier for validator operators and virtually anyone hosting Solana infrastructure.

That said, I believe my biggest bottleneck at the moment is lack of knowledge of the rustc sources necessary to understand Solana-specific changes better.
