The silly apkbuilder tool doesn't add extra native libs to an .apk
package unless their name ends with .so. It just silently ignores
them. So, force libtool to avoid versioning suffix for Android.
Yeah, unclear whether apkbuilder is what we will end up using to
construct the APKs of actual LO code using Android apps. But at this
stage when just trying to build a unit testing app, it seems to be the
simplest way to get the .apk properly signed and all to just use a
normal Ant project, and let Ant run apkbuilder.
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.
