because "when set to the default value (zero),

With "list(APPEND BENCHMARK_CMAKE_FLAGS "AA" "BB")" you don't need 
trailing whitespaces.

Please replace "set()" with "list(APPEND ... )" like above.
I suppose you mean `list(PREPEND ...)` [1] (since `APPEND` inserts
elements into the end of the list), but this is available only from
CMake version 3.15, while the minimum supported version is 2.8. So,
ignored for now.

The same already defined in test/CMakeLists.txt, could you reuse already

Yes, good catch!

I propose to use a testsuite specific timeout for tarantool-c-tests

and increase it's value instead of disabling tests.

Hint: we can set increased timeout under option LUAJIT_USE_VALGRIND only.
The problem is that this test will run for too long, so it is just
easier to skip it.

Okay.
