Yes, haven't tested with the latest SDK yet but for 5.0 and below I have it 
working.

Configure flags that I use (minus the disable/enable decoders and stuff I have 
which aren't relevant)

configure --enable-static --disable-shared --enable-pic --
sysroot="/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" 
--extra-ldflags="-arch armv7 -isysroot 
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -
miphoneos-version-min=4.0" --enable-cross-compile --arch=arm --target-
os=darwin --
cc="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --
cpu=cortex-a8 --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-
min=4.0" --disable-debug --enable-small

I also have a small patch to work around Apple gcc brokenness, which I've 
attached.
