Add support for linux-arm64 using ubuntu-24.04-arm runner

[joel16]

• Updates github workflows to use the arm64 runner for aarch64.
• Update github actions:
  • Use actions/checkout@v4
  • Use actions/setup-python@v5
  • Use actions/upload-artifact@v4

I have also updated vdpm to check for linux arch (vitasdk/vdpm#107)

This needs to run first before the VDPM pull request can be accepted.

[joel16]

@d3m3vilurr Did you get a chance to look at this? This should fix your concern with autobuilds and the VDPM pr lookup arch on linux before downloading from autobuilds.

[joel16]

@d3m3vilurr Any update on this and vitasdk/vdpm#107?

[d3m3vilurr]

sorry i'll re-review this at today night.
and thank you for your gentle ping.

@joel16 cannot build aarch64

do you have any idea?? :'(

ah config.sub file of libelf needs extra patch to arch matching

@joel16 can you support this if you having arm64 linux??

Strange.. The build was working without any patches when I last tested it. Here's the auto build from my branch: https://github.com/joel16/autobuilds/actions/runs/13215713668/job/36894737110

I'll have a look and see if I can reproduce and get back to you.

yeah. I also see it before merging.
but your recent testing ci is also broken with same reason.

our libelf is too old version, that doesn't define aarch64 arch in config.sub file.

just problem is, i'm sorry, i don't have arm64 linux machine for testing & fixing. :(

@d3m3vilurr looks like there are already PRs for buildscipts to update libelf's config.sub to support aarch64:

• Fix libelf autoconf for unsupported architectures  buildscripts#107
• Make it possible to compile with aarch64 buildscripts#122

@d3m3vilurr looks like there are already PRs for buildscipts to update libelf's config.sub to support aarch64:

* [Fix libelf autoconf for unsupported architectures  buildscripts#107](https://github.com/vitasdk/buildscripts/pull/107)

it contains multiple things to update. I'm not sure that we need all patch of them.
and also, /usr/share/misc/config.sub seems system dependent.
for example, archlinux doesn't have this.

* [Make it possible to compile with aarch64 buildscripts#122](https://github.com/vitasdk/buildscripts/pull/122)

I remember this PR, but it seems copy & paste config files from newer libelf.
so, I also don't know it's correct work or not. (so I ignored at that time..)

@SonicMastr said second patch would same as first patchset version.. but, imo if both are same and they also work as well, second one is better than first one.

[joel16]

Then I'd say we should go for the second one, I believe that should fix the build here.
