[FFmpeg-user] Compiling ffmpeg, Optimize for size

[Conor Mac Aoidh]

After adding the '--enable-small' flag, I'm having some problems 
building. It seems the build gets stuck on a file called 
'libavcodec/snowenc.d'. This command is running at 100% CPU for 20 minutes+:

//opt/android-ndk-r10e/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc 
-I. -I./ --sysroot=/opt/android-ndk-r10e/platforms/android-16/arch-arm

-Werror=missing-prototypes -MMD -MF libavcodec/snowenc.d -MT 
libavcodec/snowenc.o -c -o libavcodec/snowenc.o libavcodec/snowenc.c/

I've attached output to the configure/make steps. Anyone have any ideas 
what's going wrong?

I'm using this build script (with '--enable-small' added):

Thanks!
