cmake: enable cross compilation
When cross-compiling cmake, for example with `nix build .#pkgsCross.mipsel-linux-gnu.cmake`, the `configure` script will invoke the build platform cmake to build the host platform cmake. Usually, stdenv will automatically pass variables such as `-DCMAKE_SYSTEM_PROCESSOR` to cmake (https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/make-derivation.nix#L416), but since here cmake is invoked 'indirectly' we have to pass these parameters to the `configure` script ourselves. It appears this was (surprisingly) not necessary on versions through 3.26.4, but the update to 3.27.7 exposed that these flags were missing, causing link failures. Fixes #284734
