I made it with Python, the scripts follow:

--- main try-build.sh

#!/bin/bash

RCPT=phz@localhost

function tidy(){
   rm ../results/.config 2>/dev/null
   rm ../results/build.log 2>/dev/null
   rm ../BUILDING-NOW 2>/dev/null
}

cd ~/kernel/linux
if test -f ../BUILDING-NOW ; then
   exit 0
else
   touch ../BUILDING-NOW
   make mrproper
   cat ../config.all | ../randomize-conf.py > ./.config
   make prepare
   cp .config ../results/
   make -j 10 2>&1 > ../results/build.log
   if test $? -ne 0 ; then
     (cat ../results/.config && cat ../results/build.log) | mail -s 
'Build failed at kernel phase' $RCPT
     mv ../results/.config ../results/.config.kf.$(date +%y%m%d-%H%M%S)
     tidy
     exit 0
   fi
   make -j 10 modules 2>&1 >> ../results/build.log
   if test $? -ne 0 ; then
     (cat ../results/.config && cat ../results/build.log) | mail -s 
'Build failed at modules phase' $RCPT
     mv ../results/.config ../results/.config.mf.$(date +%y%m%d-%H%M%S)
     tidy
     exit 0
   fi
   echo OK | mail -s 'ok' $RCPT
   tidy
fi

--- the randomizer:

#!/usr/bin/python

import sys
import re
import random

netenabled = 0
token = ""

def yesno():
	if random.random()>0.5:
		return 1
	else:
		return 0


def enable_or_not(atoken):
	if yesno():
		if atoken=="CONFIG_NET":
			netenabled = 1
			print atoken+"=y"
		else:
			if atoken=="CONFIG_INET":
				if yesno():
					print atoken+"=y"
				else:
					print "# "+atoken+" is not set" ;
			else:
				print atoken+"=y"
	else:
		print "# "+atoken+" is not set" ;

switch = {
	"CONFIG_SMP": enable_or_not("CONFIG_SMP"),
	"CONFIG_SYSFS": enable_or_not("CONFIG_SYSFS"),
	"CONFIG_PROC_FS": enable_or_not("CONFIG_PROC_FS"),
	"CONFIG_PM": enable_or_not("CONFIG_PM"),
	"CONFIG_PCI": enable_or_not("CONFIG_PCI"),
	"CONFIG_BLOCK": enable_or_not("CONFIG_BLOCK"),
	"CONFIG_NET": enable_or_not("CONFIG_NET"),
	"CONFIG_INET": enable_or_not("CONFIG_INET"),
	"CONFIG_HOTPLUG": enable_or_not("CONFIG_HOTPLUG")
	}

for line in sys.stdin:
	mo = re.match("(\w+)=(.*)", line)
	if mo:
		token = mo.group(1)
	else:
		mo = re.match("# (\w+) is not set", line)
		if mo:
			token = mo.group(1)
	if token!="CONFIG_MODULES":
		switch.get(token, enable_or_not(token))
	else:
		sys.stdout.write("CONFIG_MODULES=y\n")
