* ctdb:tests: ignore SIGPIPE in unit testsMichael Adam2013-11-281-0/+2
| | | | | | | | | | | This makes scripts called in the unit tests behave like when called from ctdbd which ignodes SIGPIPE. This also makes the scrips behave the same when called from "make autotest" directly and via autobuild (python).

| | | | | | | | | To test CTDB on a cluster we need to be able to build test RPMs with relatively sane version numbers.
