We saw crashes from pthread_exit+debuggerd on LP32 (https://issuetracker.google.com/72291624), and it seems like the equivalent problem should exist with system(3). I fixed posix_spawn(3) as part of that bug, so the easiest fix is probably to reuse that. Bug: http://b/72470344 Test: ran tests Change-Id: I05f838706f2b4a14ac3ee21292833e6c8579b0d4
