Also I can't download

url = "mirror://gnu/mes/mes-${version}.tar.gz";

So I change it to

url = "https://mirrors.kernel.org/gnu/mes/mes-${version}.tar.gz";

Also change

url = "https://repo.or.cz/tinycc.git/snapshot/${rev}.tar.gz";

to

url = "https://github.com/TinyCC/tinycc/archive/${rev}.tar.gz";
