Subject: [PATCH] tests: check path tracing of old mmap syscall
* tests/old_mmap.c [!TEST_FD]: Define TEST_FD.
(main) <args1_c>: Replace 5th argument with TEST_FD.
(main): Wrap the output for the calls that do not use TEST_FD
with #ifndef PATH_TRACING.
* tests/old_mmap-P.c: New file.
* tests/pure_executables.list: Add old_mmap-P.
* tests/.gitignore: Likewise.
* tests/gen_tests.in: Add old_mmap-P test.
