This target triple was weird on multiple levels: * The `ilp32` ABI is the soft float ABI. This is not the main ABI we want to support on RISC-V; rather, we want `ilp32d`. * `gnuilp32` is a bespoke tag that was introduced in Zig. The rest of the world just uses `gnu` for RISC-V target triples. * `gnu_ilp32` is already the name of an ILP32 ABI used on AArch64. `gnuilp32` is too easy to confuse with this. * We don't use this convention for `riscv64-linux-gnu`. * Supporting all RISC-V ABIs with this convention will result in combinatorial explosion; see #20690.
