Oh ho!  The sbcl executable has already been prelinked.  When
save-lisp-and-die is called (at least with :executable t), the sbcl
executable itself is dumped with the Lisp core written into it.  So we
wind up with a prelinked image in the build directory, like so:

------------------------------------------------------------------------------
$ objdump -s /usr/bin/sbcl | grep -F prelink
Contents of section .gnu.prelink_undo:
$ sbcl
This is SBCL 1.0.30-2.fc12, an implementation of ANSI Common Lisp.
More information about SBCL is available at <http://www.sbcl.org/>.

SBCL is free software, provided as is, with absolutely no warranty.
It is mostly in the public domain; some portions are provided under
BSD-style licenses.  See the CREDITS and COPYING files in the

So this is going to hit anybody who tries to package up an executable
produced by SBCL.  Perhaps this should be noted on
https://fedoraproject.org/wiki/Packaging:Lisp.
