libc, libpthread, ld-linux, and hundreds more all must match exactly,
except of course for the pieces that you do not use at all.
See a typical list (table) at http://bitwagon.com/rtldi/rtldi.html .
If you don't want to use a matching set that sombody else has
prepared already, then start at http://sourceware.org/glibc/
and proceed to ftp://sources.redhat.com/pub/glibc/releases/
to get your own sources for glibc-2.3 and later. Building takes
a few hours using 2GB of disk, 768MB of RAM, 1GHz CPU. The
advantage is that you select exactly which features get built.
This is also the disadvantage. It'll take a few hours to read
and understand the instructions, and to coordinate environment
definitions with your operating system kernel. It's a good idea
to compare and contrast what you're trying to do, with what a
Linux distribution does (say, rebuilding a Fedora glibc-*.src.rpm.)

It is unlikely that Mathematica requires NPTL. If it does, then
its documentation should say so. It had to run on old libpthread,
and NPTL is only about 2 years old. "Ordinary" use of threads
that does not delve into implementation details runs on either,
and usually better under NPTL.
More hints: Run
readelf --version-info /path/to/mathematica
to see the GLIBC_x.y versions that are required, and
readelf --symbols /path/to/mathematica
for detailed symbol@xxxxxxxxx information. For example,
this will tell you the minimum GLIBC_2.3.z subversion you
require, and which symbol(s) trigger it.
