from the (6.4) r.out.gdal help page:

"r.out.gdal also supports the export of multiband rasters as a group, when the imagery group's name is entered as input. (created imagery groups with the i.group module)"

....

"EXAMPLES
....
Export R,G,B imagery bands in GeoTIFF format suitable for ESRI software:

i.group group=nc_landsat_rgb input=lsat7_2002_30,lsat7_2002_20,lsat7_2002_10
r.out.gdal in=nc_landsat_rgb out=nc_landsat_rgb.tif type=Byte createopt="PROFILE=GeoTIFF,INTERLEAVE=PIXEL,TFW=YES"
