[Buildroot] [PATCH 1/1] package/ffmpeg: Disable rtmpdump support when PolarSSL is enabled

Using rtmpdump with PolarSSL breaks ffmpeg configure:
/home/test/autobuild/instance-1/output/host/usr/mips64el-buildroot-linux-gnu/sysroot/usr/lib/librtmp.so: undefined reference to `havege_random'
/home/test/autobuild/instance-1/output/host/usr/mips64el-buildroot-linux-gnu/sysroot/usr/lib/librtmp.so: undefined reference to `havege_init'

This problem could be fixed by enabling POLARSSL_HAVEGE_C:
http://freetz.org/browser/trunk/make/libs/polarssl/patches/050-activate-havege-random-generator-needed-by-rtmpdump.polarssl.patch?rev=10797

This option is however accompanied by a warning in
include/polarssl/config.h:

 * Warning: the HAVEGE random generator is dependent on timing and specific
 *          processor traits. It is therefore not advised to use HAVEGE as
 *          your applications primary random generator or primary entropy pool
 *          input. As a secondary input to your entropy pool, it IS able add
 *          the (limited) extra entropy it provides.

Since rtmpdump is not a vital part of ffmpeg it is save to disable
rtmpdump support when PolarSSL is used.
