* UnoUrlTest.java lead to a scanner error due to unicode problems [1],
work around the issue by removing the offending line
* work around upstream problems with clew which is not included in
android builds but still some of the compiled files rely on it [2]
* use NDK r10e because newer NDKs don't have a README.txt and upstream
wants that file [3]
* Update the LOTarballs srclib to include the newest srclibs. If you
wonder how I created them: I built it locally without disabling
external fetching, so I got all the files needed, then I copied those
over.
* Remove some test blobs that the scanner complains about
