Very good.  Which version of glibc did you build?
Probably glibc-2.3.3, if you used the default from a recent crosstool.

Probably not headers; probably a mismatch in glibc or gcc version.
(Copying and pasting the error message into your next post would be helpful.)

Firstly, you could try linking your program with -static.
It makes for big bloated executables, but can solve
some shared library mismatch problems (by avoiding them
entirely).

If the error was a glibc version mismatch:
Find out the oldest version of glibc on any of the machines
you want to run on, then build a toolchain for that version
of glibc.
If it was a libgcc_s version mismatch: you might need to
drop back to an earlier version of gcc that matches the
libgcc on your system.

Alternately, you could install the missing shared libraries
on the target systems.
