Ricardo B. Marlière 38897ae2b0 ktest: Avoid undef warning when WARNINGS_FILE is unset 
[ Upstream commit 057854f8a5 ]

check_buildlog() probes $warnings_file with -f even when WARNINGS_FILE is
not configured. Perl warns about the uninitialized value and adds noise to
the test log, which can hide the output we actually care about.

Check that WARNINGS_FILE is defined before testing whether the file exists.
