Thanks for the reminder!

According to their earlier reservation[1] and actual vendor system
behavior, there are 3 possible values:
- loongarch64
- loongarch32
- loongarchx32
Only the LP64 ABI is fully supported by the current upstream submission.
The "loongarch32" thing might NOT be compatible with the LP64 ABI,
instead it might be something embedded-oriented, even instruction
subsets supported might differ. The "loongarchx32" is for an
n32/x32-like ABI that doesn't exist yet, and probably will never get
implemented.
Accordingly, I think we only have to care about "loongarch64" for now.
