Here is my working Configure for cross-compiling FFmpeg on iOS 6 the arch is ARMv7

NOTE: You must have to have gas-preprocessor.pl inside /usr/local/bin/ please do not continue until you have gas-preprocessor.pl on your bin directory

Download FFmpeg 1.0 "Angel" from here
Unzip it and place it somewhere i.e. your Desktop folder
Open terminal and browse to unzipped FFmpeg folder
Copy and paste the following command, (be patient will take a while)

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk' --enable-pic --enable-decoder=rawvideo --disable-asm

Now type the following command on terminal make (wait a little more)
Once it has finished now type on terminal sudo make install (wait again)
Go to /usr/local/lib to find your freshly baked armv7 libs
Enjoy!

Added Support for armv7s

This armv7s configure is totally untested and i dont really know if this would work, i don't own an iPhone 5 so we need someone to test the final armv7s libs

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7s' --extra-ldflags='-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk' --enable-pic --enable-decoder=rawvideo --disable-asm
