--enable-largefile only affects certain files which are used
internally. It doesn't automatically enable LFS on all files, as not
all of GRASS can handle large files.

Using:

	r.out.ascii mapname > outfile.txt

may work, so long as the shell was built with LFS.

For r.out.gdal, the issue is likely to be whether GDAL was built with
LFS.
