aarch64 squeak-vm

> Greetings,
>
> I have not done much in C for a couple of decades, so those bits have evaporated, but am taking a shot at getting squeak-vm(s) up on aarch64/arm64 Linux.
>
> The current Debian package runs in 64 bit mode on ARM and I have been able to build a working images from source on a Armbian/aarch64/Linux machine (LePotato/AML-S905X-CC).

> This is a superannuated (2012?) squeak-vm-4.10.2.2614, but does run in 64 bit mode on ARM.  So I have a proof of concept.  Runs Cuis/Squeak fine (but slow).

> But the C compiler (gcc) is getting confused by some x86 compile flags.

> The proximate cause is handing configure the flag "TARGET_ARCH=-m64", but it has been long enough that I have little idea where or how this script is processed.
