Add support for Android L

Browse source 
Build position-indepent executables, required for Android L (5.0+)
They also work with kitkat.

Add new maketarget "cross-android-old" that builds without PIE
for older versions.

Include both new and old versions in latest-android.zip. Add arm64.

Hopefully solves github PR #14.
