(1) TeXLive does not compile any .so files for XeTeX but rather uses the
libfontconfig.so.1 of the system installed in, e.g., /usr/lib64/.

(2) The trick is to compile the x86_64-linux binaries on a system with a
fairly old version of the GNU C Library in order not to depend on symbols
introduced more recently and not available on, e.g., CentOs5.  Compiling an
.so on such a system would help but there is still the problem of different
versions of other shared libaries.
