When compile nolibc-test.c with 2.31 glibc, we got such error:

28 | # error "rv32i-based targets are not supported"
Glibc (>= 2.33) commit 5b6113d62efa ("RISC-V: Support the 32-bit ABI
implementation") fixed up above error.
As suggested by Thomas, defining INT_MIN/INT_MAX for nolibc can remove
the including of limits.h, and therefore no above error. of course, the
other libcs still require limits.h, move it to the right place.
The LONG_MIN/LONG_MAX are also defined too.
