Sigh.

We basically need to hack https://github.com/JuliaPackaging/BinaryBuilder.jl/blob/4538e89767f3fdb11f7e192aa04bbf64f9baaf55/src/AutoBuild.jl#L1431 for Julia < 1.12.

I'd suggest skipping riscv64 for this round, we'll look into this later. It'd need regenerating llvm_full anyway, can't do anything about this right now.

[giordano]

I temporarily cancelled the jobs to do some maintenance on the build machine, will restart when done

Update: in the end I solved the issue by making a PR, I restarted the jobs here.

[giordano]

I opened JuliaPackaging/BinaryBuilder.jl#1366 about what's needed to fix the riscv64 issue.

[giordano]

For the record, this should be fixed now.

Yes, removed in #10594
