I am not sure how well supported ECW output is in GRASS or on Linux.
One possibility would be to output to a TIIF and then use
gdal_translate to convert to ECW. On Windows, I do it as follows:

gdal_translate -of ECW --config ECW_LARGE_OK YES -co blocksize=64 -co
target=91 source.tif destination.ecw

You can download the GDAL tools, which are a part of FWTools, at:
