glibc: Change riscv32-linux-gnuilp32 target triple to riscv32-linux-gnu.

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.
