Gitian crash for ARM compiling BDB depends (Bionic host) #13700
Description
I was trying a Gitian build for master at 9cdb19f? I used LXC (not Docker), but then crashes during depends make with bdb:

Gitian worked when I tested an earlier version of #13604, on a Debian 9 host and before Bionic descriptors were merged. Perhaps the changes added before merge cause a problem, or perhaps there's something about the Bionic descriptors (or host).
