fc6c17b83887ef193f2b97264b1843c94dcb915d build: make sure we can overwrite config.{guess,sub} (0xb10c)
Pull request description:
Since ea7b8528 (#26422), `autogen.sh` overwrites the `build-aux/config.{guess, sub}` files (installed there by `autoreconf`) with the `depends/config.{guess, sub}` files if these are newer.
The `autoreconf` tool copies them from it's `share/autoconf/build-aux/` directory. Specifically on NixOS, the `share/autoconf/build-aux/` files are located in the nix-store and are read-only. `autoreconf` preserves the read-only permissions when copying. Overwriting them with our `depends/config.{guess, sub}` files subsequently fails.
To make sure we can overwrite the files, set write permissions to the current user and group before overwriting. This fixes the problem on NixOS.
fixes #27873
