PX4-Autopilot: Unable to build px4 current version by cross-compilation on macOS Mojave 10.14.6

Whenever I run the make emlid_navio2_cross command in attempt to build the current master branch of the repository, I receive the following errors.

Firmware ⇨ ⇨ ⇨  △ △ △  👾  ⚡  || master || ⚡  👾   ⇨ ⇨ ⇨  make emlid_navio2_cross

I’m not 100% sure what seems to be going on here, but I can only build with make px4_sitl jmavsim not gazebo either.

To note:

The current path to my gcc &g++ are as follows: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++

I have also ran the sequence below in attempt to fix: make clean make submodules clean git submodule update --init --recursive

Similarly, also running this: sudo rm -rf /Library/Developer/CommandLineTools sudp xcode-select --install sudo xcode-select --reset

Any help would be greatly appreciated. Thank you!
