My suggestion for fix: Recompile under a 64-bit system and distribute mentioned 64-bit version.
Here's the log when I run graal4setup:
NPC Code:
# Preparing: Graal Online
# Checking for required C library versions ... failed
# FAIL:
# Your copy of glibc, a core system library, is too old for this package.
# You need at least the following symbols in glibc: GLIBC_2.0.
#
# This error normally means that whoever built the package did not build it correctly.
# Please report the contents of this message to the provider of this package, and
# ask them to rebuild it using apbuild.

# Upgrading glibc is highly dangerous, so we recommend in this situation that you
# compile the app you want to install from the sources if possible. Sorry 
FAIL: Unable to prepare package Graal Online.
I appearently have version 2.3.x or higher.
