Issue

build failed for reasons:

[100%] Built target libpng
make[3]: Leaving directory /home/marcin/koreader/base/thirdparty/libpng/build/arm-linux-androideabi' make[2]: Leaving directory /home/marcin/koreader/base/thirdparty/libpng/build/arm-linux-androideabi'
cp -fL /home/marcin/koreader/base/thirdparty/libpng/build/arm-linux-androideabi/libpng-prefix/src/libpng-build/.libs/libpng16.so.16 build/arm-linux-androideabi/libs/libpng16.so.16
cp: cannot stat '/home/marcin/koreader/base/thirdparty/libpng/build/arm-linux-androideabi/libpng-prefix/src/libpng-build/.libs/libpng16.so.16': No such file or directory

make[1]: Leaving directory `/home/marcin/koreader/base'
Makefile:52: recipe for target 'all' failed
make: *** [all] Error 2

libpng16.so.16 doesn't exist but exist libpng16.so (without '.16') under that path:

~/koreader/base/thirdparty/libpng/build/arm-linux-androideabi/libpng-prefix/src/libpng-build/.libs$ ls libpng16.*
libpng16.la libpng16.lai libpng16.so

Steps to reproduce

git clone https://github.com/koreader/koreader.git
cd koreader && ./kodev fetch-thirdparty && ./kodev release android

the same for:
libfreetype.so.6
libjpeg.so.8
(.. and many more).

workaround - paste one by one after each error:
