+Only import bz2 python module when needed
+
+The js2c.py script imports the bz2 module unconditionnally, which
+would require us to build the bzip2 support in host-python. Since in
+fact bzip2 support is not technically used when building this package,
+we ensure that the bz2 module is only imported when needed.
