Since these commits

http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=db7f1c7c5a1d37e7f4da64a79a97bea1c4b6e9f8
compilation on arm4/arm5 fails:
libavcodec/libavcodec.so: undefined reference to
`ff_startcode_find_candidate_armv6'
Because libavcodec/arm/Makefile contains
ARMV6-OBJS-$(CONFIG_STARTCODE) += arm/startcode_armv6.o
function ff_startcode_find_candidate_armv6 is not included for older ARM
archs. The bug was found during automatic buildroot builds:
http://autobuild.buildroot.net/results/ec7/ec71e4f16ee9106747dff5f15999cbd17903e76f//build-end.log
Quote from configure summary:

Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.
