[XeTeX] Buggy behaviour of install-xetex script

[Wlodek Bzyl]

   On Fedora 5 the following line

      texbin=`readlink ${texbin}`

   yields

      pdfetex

   instead of the full pathname

     /usr/bin/pdfetex

   To force the readlink program to produce the full pathname
   it suffices to call it with `-f' option:

      texbin=`readlink -f ${texbin}`
