Can't compile on Arch

Compiling on Archlinux fails with the following error message:

what gcc version you used? ( gcc 4.7.x is not supported; you'll need to upgrade to gcc 4.9.x or later. )

Hey @XK4MiLX Arch generally uses the latest version of everything:

➜ gcc --version
gcc (GCC) 10.2.0

Hi,
Just a side node: For official release of arm, we are compiling it using cross compile on ubuntu 16. You can check out our travis file of how it is done.
