I don't think it makes much sense. We have no networking support, why should we have domain and host names?

Good point. I've updated patch.

Looks like non-networking profiles are currently broken because of
_IL_InfoMethods_GetNetBIOSMachineName function in engine:

gcc -DHAVE_CONFIG_H -I. -I. -I../include    -I../libffi/include -fno-gcse -fno-inline-functions                         -fno-unit-at-a-time -I../support       -I../libgc/include -I../include                                          -I../libffi/include -I. -DBUILD_PROFILE_NAME="\"kernel-fp\"" -g -O2 -Wall -c ilrun.c

collect2: ld returned 1 exit status

I don't think it's needed for non-networked profile, so this patch just
disables it along with _IL_InfoMethods_GetUserDomainName function that
calls it.
