If you are experiencing problems while building, getting out of memmory:

[230049.374808] lowmemorykiller: Killing 'genautomata' (9796), adj 0,
[230049.374816]    to free 899056kB on behalf of 'kswapd0' (27) because
[230049.374823]    cache 5912kB is below limit 6144kB for oom_score_adj 0
[230049.374829]    Free memory is -1276kB above reserved

we need to "disable" lowmemmorykiller:

echo '9999' > /sys/module/lowmemorykiller/parameters/adj
echo '1' > /sys/module/lowmemorykiller/parameters/minfree
