lib: Add stale 'raid6' directory to .gitignore file

I keep having to do this, because people think they can just move
directories around and move the gitignore files around with them.

You really can't do that - the old generated files stay around for
others, and still need to be ignored in the old location.

So when moving gitignore entries around because you moved the files (or
when moving a whole gitignore file around because the directory it was
in moved), the old gitignore situation needs to be dealt with.

Yes, those files may have moved in *your* tree when you moved the
directory. And yes, new repositories will never even have seen them.
But all those other developers that see the result of your move still
likely have a working tree with the old state, and the files that were
hidden from git by an old gitignore file do not suddenly become
relevant.

fortify: refactor test_fortify Makefile to fix some build problems

There are some issues in the test_fortify Makefile code.

Problem 1: cc-disable-warning invokes compiler dozens of times

To see how many times the cc-disable-warning is evaluated, change
this code:

$(call cc-disable-warning,fortify-source)

to:

$(call cc-disable-warning,$(shell touch /tmp/fortify-$$$$)fortify-source)

Then, build the kernel with CONFIG_FORTIFY_SOURCE=y. You will see a
large number of '/tmp/fortify-<PID>' files created:

$ ls -1 /tmp/fortify-* | wc
80 80 1600

This means the compiler was invoked 80 times just for checking the
-Wno-fortify-source flag support.

$(call cc-disable-warning,fortify-source) should be added to a simple
variable instead of a recursive variable.

Problem 2: do not recompile string.o when the test code is updated

The test cases are independent of the kernel. However, when the test
code is updated, $(obj)/string.o is rebuilt and vmlinux is relinked
due to this dependency:

$(obj)/string.o: $(obj)/$(TEST_FORTIFY_LOG)

always-y is suitable for building the log files.

Problem 3: redundant code

clean-files += $(addsuffix .o, $(TEST_FORTIFY_LOGS))

... is unneeded because the top Makefile globally cleans *.o files.

This commit fixes these issues and makes the code readable.
