Exactly this has been answered in the mail:

sqlitejdbc does this in order to provide a cross-platform (pure Java) 
sqlite
jdbc driver. If one plans to compile the resulting jarfile with gcj 
there is no
need to do this trick in the first place.

sqlitejdbc provides a build option not to include the MIPS emulator and 
use JNI
to access the native compiled sqlite library.
