[tex-live] TL installer xz.x86_64 expects GLIB_C 2.6

$  uname -a

/usr/local/texlive/2010/tlpkg/installer/xz/xz.x86_64-linux:
/lib64/libc.so.6: version `GLIBC_2.6' not found (required by
/usr/local/texlive/2010/tlpkg/installer/xz/xz.x86_64-linux)

$ strings xzdec.x86_64-linux | grep GLIB
GLIBC_2.2.5
$ strings xz.x86_64-linux | grep GLIB
GLIBC_2.2.5
GLIBC_2.6            <-------------- RHEL has GLIBC_2.5
GLIBC_2.3

I use the i386-linux binaries on this system, so it is the installer
that is invoking the x86_64linux version of xz.  A
workaround should be to replace the x86_64 version with the i386 versiion:

$ strings xz.i386-linux | grep GLIB
GLIBC_2.2
GLIBC_2.0
GLIBC_2.1
GLIBC_2.3

Since I just did an update, it isn't obvious how to test the backups
without waiting for an update to appear.
