Subject: test: flush stdout after forking
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b73c8eded7da56c8689fee15007f632fb5825c10;p=dpdk.git

test: flush stdout after forking

meson test was not capturing the intended output from the child
process; force a flush to ensure it reaches the test log.
