Removed cc from the update, as it was the cause of the riscv32 error.

[ehuss]

@alexcrichton risc-v support was added to cc in rust-lang/cc-rs#428, rust-lang/cc-rs#429, rust-lang/cc-rs#430. I'm not up to speed with how bootstrap interacts with cc, or the consequences of those PRs.

I'd like to move this PR forward without cc and deal with it separately.

I also don't know how the risc-v targets were linking without a risc-v gcc toolchain installed. If you want to give some guidance on what needs to change, I can look at it.

[alexcrichton]

@ehuss the support there is largely just in the form of defaults, it looks like the default compiler selection just wasn't available. I think this probably falls into one of two buckets:

• One is that we have a riscv toolchain and it's just not being used. This would be fixed by setting the right CC_... env vars in the containers.
• Another is, as you pointed out, we don't even have a riscv toolchain. In that case the "detected toolchain" was actually bogus and used it would cause problems. It's possible to configure our build though to not actually need a C toolchain for just producing libstd. I'd have to investigate to see what's the case here.

If there wasn't actually a riscv toolchain at all we probably just need to update rustbuild to stop asserting that one exists for riscv.

[mati865]

To save your time, it's just libstd build and C toolchains for RISC are not installed.
