It has been there since the boost package was added:

But I don't know enough about boost to know if it really is needed.
I must say that libbz2 is probably not your biggest concern compared to
the size of libstdc++ and the template heavy boost code:
-rwxr-xr-x 1 peko peko 73K Jun 3 20:28 output/target/usr/lib/libbz2.so.1.0.6
-rwxr-xr-x 1 peko peko 624K 2013-06-03 19:42 output/target/usr/lib/libstdc++.so.6.0.16

Perhaps it used to be a dependency of something, and isn't anymore? We
have relatively recently (February) bumped the boost version to 1.53.0.
