Subject: support busybox for manual trace tests
X-Git-Tag: v1.9.1~378
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=a5723f5808f5c93ef4ae20ed11523c97db0e6269;p=lttng-ust.git

support busybox for manual trace tests

The busybox version of find does not support using -L, and it does not
appear to be needed in order to pass the test.  In the interest of
being able to run internal UST tests on a busybox based rootfs,
appropriately detect if -L is available as an argument to find and use
it when it is available.
