Build: Adapt Terapines Zcc(>=4.1.2) compiler options to match STDCLIB makefile variable. (#63)

* [terapines.mk] Use different --config options for each STDCLIB (Require after zcc 4.1.2).

* [zcc] Remove the -fuse-size-lib compile flag
This option is no longer effective in zcc version 4.1.2 and later.
This option searches for C libraries under the size directory and is now being deprecated.

* Build: Update the built-in basic library link option of ZCC Toolchain

* docs: Add the version description of zcc toolchain to prevent users from making mistakes during use
