An Android app always runs in the context of a Java (well, Dalvik)
virtual machine.
Sure, there will now be some Java-related compilation errors here and
there when cross-compiling for Android. Use --without-java if they
disturb, until I have fixed them.
In the spirit of 12759f67a3, change
external lib's config.sub to eat the arm-unknown-linux-androideabi
host os string. Also, permit shared libs again - seems Android can
handle those.
Added dictionaries to cross-build-toolset - idxdict is needed.
Should build up to sfx2 - some residual static lib issues there,
and in raptor.
