Subject: lava: Use custom timeout function for make check
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=046a1ad96998a0482953eef335447c6f39d16eb1;p=lttng-ci.git

lava: Use custom timeout function for make check

This allows us to send SIGABRT and get coredumps for the state of the
binaries that are interesting.
