tcc.c: fix previous commit "Use CString to concat linker options"

- remove redunant else branch
- zero-terminate linker_arg
- declare cstr_xxx as PUB_FUNC
  (which are functions used in tcc.c but not in the libtcc API.
   Useful for a tcc(.exe) that uses the libtcc.(so/dll))
- while at it, export PUB_FUNCs from dll
