your app tries to use a libc version from the last century ... (ubuntu
exists only since 2004)

from this link you can tell what the current version of GLIBC on your
install is (2.17)

objdump -x /lib/arm-linux-gnueabi/libc.so.6|grep GLIBC

will tell you how far backwards compatible the used libc is ...
... and you will notice it only goes back to 2006 (GLIBC_2.4)

i think for something that old you might need a chroot (if your app is
commandline only) or a VM to run a similar ancient distro release in
which you run your app ...

and indeed alternatively you can port your app to a recent libc if you
have the source.
