IIRC it was planned to be something like the MIPS n32, but due to the later shift to the RISC-V-like model it should no longer exist. The "LPX32" ABI should never see the light of day.

But again here I'm just updating the script to match the upstream behavior. If `loongarchx32` should be deleted here, then the upstream config.git should get updated too.

I just found out this a few minutes ago (in my test repo I just copied over the upstream script so I didn't notice). Fixed.
