br-reproduce'd build doesn't fail or take a long time on
host-libsodium (below).  I also checked my env, no define and I don't
have asan on this machine.  Only difference now would be executing it
under the python autobuilder env. I'll see if I have autobuilder logs
from these failures (maybe I should add some logging, the signal test
maybe messes with the cmd shell?)
