[PATCH] os/osinit: Allow builders to --disable-segv-handler

[Colin Walters]

Modern operating systems come with systemwide "crash catching"
facilities; for example, the Linux kernel can now pipe core
dumps out to userspace, and programs like "systemd-coredump"
and "abrt" record these.

In this model, it's actively counterproductive for individual
processes to catch SIGSEGV because:

1) Trying to unwind from inside the process after arbitrary
   corruption is destined to fail.
2) It hides the fact that a crash happened at all - my OS test
   framework wants to know if any process crashed, and I don't
   want to guess by running regexps against /var/log/Xorg.0.log
   or whatever.
