I also noticed that gdb-11.1 failed to build on core-updates on
riscv64-linux. I can confirm that gdb-12 does build on riscv64-linux on
core-updates. I haven't tried yet to use gdb-12 in place of gdb-11 in
the rust tests, but I assume it would work. I'll test it out on x86_64
on core-updates to see if it works.

It sounds like as it currently stands neither aarch64 nor riscv64 have a
working rust on core-updates. I suppose, in order to decrease the number
of rebuilds, we could introduce gdb-11.2 and use that as the gdb input
in rust for those two architectures until I can either switch everyone
to 11.2 in the rust-team branch or switch everyone to gdb-12.
