Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended
the symbol version to symbols shown in reloc dumps.
[BZ #16512]
* scripts/localplt.awk: Strip off symbol version.
* NEWS: Mention bug fix.
GNU_IFUNC are shown by readelf in 'Relocation section' value as
"symbol()" instead of expected hexadecimal value. This causes the
check-localplt script to ignore potential PLT stub begin generated
by wrong IFUNC usage. This patch changes the localplt script to
emit such PLT cases.
