Why is this necessary? scons? I know that xcode always puts static libraries
into the product dir too.

If this is just for scons, I'd probably rather use `test =
TestGyp.TestGyp(formats='!scons')` to disable the test on scons.

Yep.  I changed the condition; skipping the test seems excessive since it all
works as expected otherwise.

+  # For make/msvs/ninja, we expect the library to be copied to $PRODUCT_DIR.
+  standalone_static_library_dir = test.EXECUTABLE
+else:
+  # Otherwise, we expect the library to be copied to the shared lib dir.
+  standalone_static_library_dir = test.SHARED_LIB
+path_to_lib = os.path.split(
+    test.built_file_path('mylib', type=standalone_static_library_dir))[0]
+lib_name = test.built_file_basename('mylib', type=test.STATIC_LIB)
+path = os.path.join(path_to_lib, lib_name)
+test.must_exist(path)
+
+# Verify that the program runs properly.
+expect = 'hello from mylib.c\n'
+test.run_built_executable('prog', stdout=expect)
+
+# Verify that libmylib.a contains symbols.  "ar -x" fails on a 'thin' archive.
+if test.format in ('make', 'ninja') and sys.platform.startswith('linux'):
+  retcode = subprocess.call(['ar', '-x', path])
+  assert retcode == 0
