Subject: [PATCH] Add linking options for tinycc backend (#24750)

### Issue

When using `tcc` as backend to compile a trivial program

```
nim c  --cc:tcc  --skipCfg a.nim
```

, errors reported:

```
tcc: error: undefined symbol 'fabs'
```

### Solution

`fabs` belongs to libm. With these two options added, one can compile
with an additional clib option:

```
nim c  --cc:tcc  --skipCfg --clib:m a.nim
```
