Within run_tests target, the whole script needs to be executed within
the same shell and not as separate subshells, so the initial test_num
variable set to 0 is still present when executing "test_num=`echo
$$test_num+1 | bc`;".

Demonstration of the issue (make run_tests):

TAP version 13
(standard_in) 1: syntax error
selftests: basic_test
========================================
ok 1.. selftests: basic_test [PASS]
(standard_in) 1: syntax error
selftests: basic_percpu_ops_test
========================================
ok 1.. selftests: basic_percpu_ops_test [PASS]
(standard_in) 1: syntax error
selftests: param_test
========================================
ok 1.. selftests: param_test [PASS]

With fix applied:

TAP version 13
selftests: basic_test
========================================
ok 1..1 selftests: basic_test [PASS]
selftests: basic_percpu_ops_test
========================================
ok 1..2 selftests: basic_percpu_ops_test [PASS]
selftests: param_test
========================================
ok 1..3 selftests: param_test [PASS]
