This improves the failure output by pointing to the failing line at the
top level of the test, e.g.:
# test_number: EXPECTATION FAILED at lib/printf_kunit.c:103

When cross compiling with clang we need to specify the target in
CFLAGS and cc-option will fail to recognize target-specific options
without it. Add CFLAGS to the CC invocation in cc-option.

The introduction of the realmode_bits variable is necessary to
avoid make failing to build x86 due to CFLAG
Similar to x86 the ppc boot code does not build with GCC 15.
Copy the fix from
commit ee2ab467bddf ("x86/boot: Use '-std=gnu11' to fix build with GCC 15")

In relocate_32.S, function clear_utlb_entry() goes into real mode. To
do so, it has to calculate the physical address based on the virtual
address. To get the virtual address it uses 'bl' which is problematic
(see commit c974809a26a1 ("powerpc/vdso: Avoid link stack corruption
in __get_datapage()")

Convert the printf() self-test to a KUnit test.
In the interest of keeping the patch reasonably-sized this doesn't
refactor the tests into proper parameterized tests - it's all one big
test case.

Move all tests into `printf_test_cases`. This gives us nicer output in
the event of a failure.
Combine `plain_format` and `plain_hash` into `hash_pointer` since
they're testing the same scenario.

This is one of just 3 remaining "Test Module" kselftests (the others
being bitmap and scanf), the rest having been converted to KUnit.
I tested this using:
$ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 printf
I have also sent out a series converting scanf[0].
