gcc: error: unrecognized command line option '-mlongcalls'

I'm trying to build the toolchain by executing

$ make

The build fails with

gcc: error: unrecognized command line option '-mlongcalls'

In the config.log I have the following lines:

```sh configure:2884: $? = 0 configure:2873: gcc -v >&5 Using built-in specs.

I'm building on NixOS, using the following

shell.nix:

```nix with import { }; let packages = (with pkgs; [ gcc ncurses gdb python ]); in pkgs.mkShell { buildInputs = packages; hardeningDisable = [ "all" ]; shellHook = '' export hardeningDisable=all ''; } ```

I just re-run a Travis CI build, which is green: https://travis-ci.org/github/pfalcon/esp-open-sdk/builds/672660589 . You can see how the build log differs from your results, and think what to do about (the easiest solution might using known-working OS in a container or similar).

Thanks. I've got it working by "manually" building the lx106-hal as described here. Just tried compiling and uploading the "blinky" example without any issue.
