Excess empty line, please remove.

realloc -> realloc()

to highlight that realloc is a function

I would add a prefix VALGRIND_ and put variable outside of condition. 
Feel free to ignore.

In the commit message, you say that VALGRIND_OPTIONS is an env variable.

However, it is not:


$ VALGRIND_OPTIONS=XXXX ctest -R 
test/tarantool-tests/arm64-ccall-fp-convention.test.lua --verbose

<snipped>


Also, replace "valgrind" in LUAJIT_TEST_COMMAND by ${VALGRIND_BIN} and

put "find_program(VALGRIND valgrind)" before:

I would add default set() with "LUAJIT_TEST_COMMAND" and remove a second 
branch:


set(LUAJIT_TEST_COMMAND "${LUAJIT_TEST_BINARY} -e 
dofile[[${LUAJIT_TEST_INIT}]]")
if(LUAJIT_USE_VALGRIND)

<snipped>

set(LUAJIT_TEST_COMMAND "valgrind ${VALGRIND_OPTIONS} 
${LUAJIT_TEST_COMMAND}")

endif()
