[ Upstream commit a9cdc1c5e3700a5200e5ca1f90b6958b6483845b ]
Commit 463538a383a2 ("perf tests: Fix test 68 zstd compression for
s390") inadvertently removed the -g flag from all platforms rather than
just s390, because the [[ ]] construct fails in sh. Changing to single
brackets restores testing of call graphs and removes the following error
from the output:
$ ./perf test -v 85
85: Zstd perf.data compression/decompression :
--- start ---
test child forked, pid 50643
Collecting compressed record file:
./tests/shell/record+zstd_comp_decomp.sh: 15: [[: not found
