Use TARGET_COMPUTE_MULTILIB to search the multi-lib reuse for riscv*-*-elf*,
according following rules:
1. Check ABI is same.
2. Check both has atomic extension or both don't have atomic extension.
- Because mix soft and hard atomic operation doesn't make sense and
won't work as expect

How did you test that?

riscv_multi_lib_check(int, const char**)':

Hi Andreas:
Hm, I should change my default gcc on Ubuntu, I didn't got this
when build with GCC 7, and can be reproduced by GCC 11,
Will summit patch once I test done.

I find the other_cond support a bit confusing. Is this for -mcmodel
perhaps? Why not just say that if so?

I suppose we might have other multilib options other than -march,
-mabi and -mcmodel,
so I keep the flexibility here.
