The line should match the last line of ld-powerpc/tlsexe32.r.  Three
possibilities occur to me that might cause this:
1) There really is a duplicate globel ie0 symbol, or readelf is
   duplicating an output line.
2) expect/dejagnu is duplicating output lines to dump.out, or reading
   that file back when matching regexps duplicates the last line.
3) The last line of tlsexe32.r is dropped from the git checkout, or
   when matching regexps.

None of these things happen elsewhere as far as I know.  ie. the build
bot is broken.
