I could build the lib with the gcc-3.4.0-glibc.2.3.2 cross compiler (binary from http://developer.osdl.org/dev/plm/cross_compile/). But I'm not sure if linking libraries compiled from different versions of gcc will correctly link. Probably we (our customer) have to try.

Yeah, probably want to match versions.

gcc-3.2.3 was early days for x86_64, though, so you might want
to find the source for the exact compiler used on your target,
and build that instead of vanilla gnu.org sources.  It may
have a patch for this problem.
