I don't understand your problem.  You're creating an executable that
uses new features of ELF which were not implemented in glibc 2.1.
glibc 2.1 complains that it doesn't understand this executable.  The
obvious fix is to make glibc 2.2 understand the executable, then use
glibc 2.2.  Why do you want to do something different?
