I fear I dont really have the time to test this, but the i386 nodes used
for reproducible builds testing have 10 cores and 36gb ram, plus we have
several quad and octo core armhf systems (with 2-4gb ram).
Maybe Mattia can test that? (and what exactly? Apply the patch here,
sure and then build which package? (for the unlikely case that I'll find
time soon…)
