GLibC version incompatibility for mostly static native image

[ole-ve]

Describe the issue
Building and running a mostly static native image on Ubuntu 22.04 works fine, but when executing this same native image on Ubuntu 20.04, there seems to be a version incompatibility of GLibC. Both systems run on amd64.

Steps to reproduce the issue

1. Create any basic (Gradle) Java project. Example
2. Build a native image from this project (./gradlew nativeCompile) on an Ubuntu 22.04 machine
3. Execute this image on an Ubuntu 20.04 machine (e.g. in a Docker container)

Describe GraalVM and your environment:

• GraalVM version: GraalVM CE 23.0.0-dev-20230303_0222
• JDK major version: 17
• OS: Ubuntu 22.04
• Architecture: AMD64

More details
I have also checked that the issue is not related to the Gradle plugin but just provided an example with it for convenience.

The error output when executing on Ubuntu 20.04:

/app: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /app)
/app: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /app)

I couldn't find information regarding incompatibility between linux distros running different versions of GlibC. But that shouldn't be an issue, right?

Thanks for the ticket, @ole-ve.

This is somewhat expected, at least on Linux and macOS. For best compatibility, build on the oldest OS (or oldest GLibC) you want to target.
