Android is not a developper friendly target.
For example, log2() is available only since ABI 18.
So, using LUA_USE_C89 is a conservative choice (not an optimal
choice), like with Windows.
On Android, like on Windows, we don't need LUA_C89_NUMBERS.
I think that LUA_USE_C89 + LUA_C89_NUMBERS is only for very old
compiler/toolchain.
It is the reason for my variant 2, where the dependency between
LUA_USE_C89 and LUA_USE_C89 is removed.
