Here's the information from the README.Linux file about this problem:

  The linker can't find -lieee

  This can happen because your libraries don't match your version of
  gcc.  Some recent Linux distributions don't include a libieee.a file
  because IEEE support is now the default and the library is no longer
  needed, but the gcc specs file still adds -lieee to the linker command
  if gcc is invoked with the -mieeefp flag.  I believe that you should
  be able to fix this by editing the gcc specs file.  In it, you should
  find something like this:

    %{!shared: %{mieee-fp:-lieee} %{p:-lgmon} %{pg:-lgmon} \
    %{!ggdb:-lc} %{ggdb:-lg}}

  changing it to

    %{!shared: %{p:-lgmon} %{pg:-lgmon} %{!ggdb:-lc} %{ggdb:-lg}}

  should keep gcc from adding -lieee to the link command.  You can find
  the location of the specs file by running the command gcc -v.

  If you can't edit the gcc specs file for some reason, another solution
  that should work is to create an empty libieee.a file in the Octave
  src directory using the command:

    ar cq libieee.a

  NOTE: you should fix this problem (either by editing the specs file or
  by creating the library) *before* running configure and compiling
  Octave.  Otherwise, configure may incorrectly determine that your
  system doesn't have support for some IEEE math functions.
