Please let me know if I'm missing something here?

From what I can see, you need to install gcc.

gcc has already been installed on the machine.

You simply can't be building this on an arm device, as you have some hardcoded x86_64-linux-gnu-gcc expectation of a gcc binary in some makefile probably. You can try and pretend you have it like so:

ln -s `which gcc` $(dirname `which gcc`)/x86_64-linux-gnu-gcc
but its not a guarantee it'll have the same parameters, still you can try.

Now it's throwing GCC error.
