I don't know which output driver you use (EHdr, ENVI etc.), but they aren't 
likely to produce a .blw worldfile as they will generate a text header file 
specific to the format.

To generate a .blw file you can do:

gdal_translate your_input.tif tmp.tif -co TFW=YES

This will generate a tmp.tfw file. Just rename it to .blw and with the 
basename of your BIL output file.
