pelya 565f159a20 Revert "Revert "Disabled STLPort built into NDK in favor of my own STLPort, disabled cin/cout/cerr in my STLPort"" 
STLPort inside NDK R5 crashes when accessing stdout the smae way as mine built-in STLPort, but I have the possibility to change my own STLPort sources

This reverts commit 4a02eeeded.
