The source-tarball genrated by source-build should work everywhere

[omajid]

Historically, source-build has generated fairly portable source tarballs. If I built the source-build tarball on RHEL 7, for example, I have been able to use it to build source-build on Fedora 29, 30 and 31, as well as RHEL 8.

With the recent reduction in prebuilts, some of this functionality has regressed. Now, I need to build source-build on each platform/architecture. I can't re-use the RHEL 7 tarball on Fedora. I can't build the source-tarball I built on Fedora 31 in Fedora 32.

I think the eventual goal, fitting in with the 0 prebuilts goal, is to not have anything in the source-tarball that's OS/architecture specific. The same source-tarball should be build-able everywhere; the individual doing a build should supply a working SDK (and/or other OS-specific dependencies) to source-build.

I need to build source-build on each platform/architecture.

Is it a dependency on the rid of the platform that was used to generate the tarball?
Or another platform dependency?

This is related to #298 (create linux-x64 compatible tarball for each release).

I wonder if we can generate a tarball for the fedora-x64 rid and use it on multiple versions of Fedora...

Bringing this one up for triage again because I believe it's relevant to some issues we had with recent releases.

With all the bootstrap work complete, I have had decent success now using the same tarball for building 3.1 on Fedora 32 and 33 on x86_64 and also, separately, on Fedora 33 on x64 and arm64. Are there still any known issues here?

Edit: I am assuming that distro-specific build tools, such as a prebuilt SDK are available separately. Unless we want to create uber-tarballs containing multiple prebuilt SDKs for multiple architectures?
