Once there are more than a certain number of kernel config options set (this happened for us with kernel 4.17), the method of passing those as command line arguments exceeds the maximum number of arguments the shell supports. This causes the whole testsuite to fail. Instead, create a temporary file and modify its contents so that the config option variables are exported. Then this file can be sourced in before running the tests.
