[BRLTTY] Brlapi on Android

[Peter Lecky]

Hello to all again,

I tried to compile older sources, concretely version 6.4 and it works as 
expected with that one line tweak in common.mk file.

So it seems for now, that Android bindings in master branch are broken 
for now. And it is perfectly enough to enforce build sistem to produce 
libraries without version suffix to have working library with older 
stable versions.
