Subject: [PATCH] build: allow deactivating the crash handler at build time
(#1166)
SLADE's own crash handler has two problems:
* it inhibits the generation of a proper crashdump
* it calls functions that not async-signal safe and/or re-entrant,
such as malloc (by way of backtrace(3)), which can lead to a hang
when the initial crash happened in malloc,
Fixes: #1166
