Patching toolchain sources
ERROR: Could not patch sources.

Answer 1

Fixed by Google in ndk-9b, now it's patching without problems

Answer 2

You could try to run patch-sources.sh directly, with debugging enabled. With a little luck, it will give you some clues.

bash -x patch-sources.sh \ 
/tmp/ndk-USER/android-ndk-toolchain-DATE \
/PATH/TO/YOUR/NDK/build/tools/toolchain-patches

You can do the same with the download-toolchain-sources.sh script as well - this is how I got the arguments for patch-sources.sh.

You could also pass "--verbose" to either script.
