on C toolchain installed in the system

-C soft-float=val -- use soft float ABI (*eabihf targets only) (default: no)
-C split-debuginfo=val -- how to handle split-debuginfo, a platform-specific option
-C strip=val -- tell the linker which information to strip (`none` (default), `debuginfo` or `symbols`)
