[Buildroot] lame linking issue

[Yegor Yefremov <yegor_sub1@visionsystems.de>]

I'm using the latest git version of BR and wanted to build lame-3.98.4. During linking phase I got following errors:

parse.o: In function `local_strcasecmp':

Any idea? 

Some toolchain details:

uClibc: 0.9.32
GCC: 4.6.1

I could also post the whole config file.
