NOOB Build Help for aarch64 Linux (Armbian) [platform not supported: aarch64-linux-mes]

[ken . dickey]

Greetings,

Noted your work and trying to take a look.  Have not used C/x86 much for 
a couple of decades. Mostly aarch64 & some riscv64. Have Scheme and 
Smalltalk experience.

Can some kind person point me in the right direction?

Thanks a bunch!
