- Android: enable debug logs in debug build type
- Android: enable debug in native lib

of local references.

Now espeak should not crash on some android devices.

See commits ae97fa16 and a178ea1b.

I really wonder why the code comment says.
	case NUM2_THOUSANDS_VAR2: // lang=cs,sk
and option 4 was used for Czech, and this is not the case when this
option fits the language, just the opposite.
it reads 10000000 as 10000, 11000000, as 11000, and so on
almost the same problem was in the Russian language, only it consisted
in the fact that the var_1 itself was not made correctly. And here the
variant is commented on as the one that is used in the Czech language,
but it is not used there. And the worst thing is that everyone does not
pay attention to it, well, it reads the wrong number, well, okay.
