Merge pull request #24305 from hanliutong:toolchain
cmake: Fix riscv-gnu toolchain file. #24305

cmake(3.22.1) failed without the keyword `PATHS` on my device when I manually set `TOOLCHAIN_COMPILER_LOCATION_HINT` in command. And this patch is going to fix this issue.

[CMake Doc](https://cmake.org/cmake/help/latest/command/find_program.html):
> find_program (
>           <VAR>
>           name | NAMES name1 [name2 ...] [NAMES_PER_DIR]
>           [HINTS [path | ENV var]... ]
>           [PATHS [path | ENV var]... ]
