multimedia/libkate: [patch] fix "undefined reference to yylex" build error on Linux

[Matthias Ferdinand <mf+ml.pkgsrc-users%netzwerkagentursaarland.de@localhost>]

Hi,

on Linux (Ubuntu 10.04, Debian 8), multimedia/libkate fails to build
with the following error:

    /bin/bash ../libtool  --tag=CC   --silent --mode=link gcc -Wall -W   -I/opt/pkgsrc/include -I/opt/pkgsrc/include/libpng16  -O2 -I/opt/pkgsrc/include -I/usr/include  -L/opt/pkgsrc/lib -Wl,--enable-new-dtags,-R/opt/pkgsrc/lib -L/usr/lib -Wl,--enable-new-dtags,-R/usr/lib -o kateenc kateenc-kateenc.o  kateenc-kate_lexer.o  kateenc-kate_parser.o kateenc-kpng.o ../lib/liboggkate.la ../lib/libkate.la -L/opt/pkgsrc/lib -Wl,--enable-new-dtags,-R/opt/pkgsrc/lib -logg -L/opt/pkgsrc/lib -Wl,--enable-new-dtags,-R/opt/pkgsrc/lib -lpng16 -lfl
=>  /opt/pkgsrc/work/pkgsrc/multimedia/libkate/default/.buildlink/lib/libfl.so: undefined reference to `yylex'
    collect2: error: ld returned 1 exit status
    *** Error code 1

I found an existing patch via
http://www.linuxquestions.org/questions/slackware-14/cant-compile-libkate-on-slackware64-current-4175545811-print/
and reformatted it for pkgsrc (s. attachment)

On NetBSD 6, libkate builds ok with or without this patch.

Regards
Matthias
