Cross compile issue LibreELEC x86_64 —> aarch64

[heitbaum]

Thought to give zlib-ng a try.

compiling using:

• PROJECT=Generic ARCH=x86_64 TARGET_CPU=tigerlake IMAGE_SUFFIX=tigerlake s/build zlib worked, I will try a full build next.
• PROJECT=Amlogic ARCH=aarch64 DEVICE=AMLG12 UBOOT_SYSTEM=odroid-n2 s/build zlib Failed

A full x86_x64 (not cross compiled) is working

A quick run test is ok. Will need to do some full testing, but as a start 👍no performance testing yet.

[nmoinvaz]

I believe your aarch64 issue is fixed by #898. Have you tested against latest develop?

[Dead2]

This should work in 2.0.2, please reopen if it does not.

@nmoinvaz @Dead2 - great turn around time 👍

Build tested for aarch64 AMLG12, will need to do a run test. But will leave it in my dev tree now and put it through it’s paces.
