4e1c97052b liblzma: Use attribute no_profile_instrument_function with ifunc.
Thanks to Sam James for determining this was the attribute needed to
workaround the GCC bug and for his version of the patch in Gentoo.

ed957d3942 Build: Require attribute no_profile_instrument_function for ifunc usage.
Using __attribute__((__no_profile_instrument_function__)) on the ifunc
resolver works around a bug in GCC -fprofile-generate:
it adds profiling code even to ifunc resolvers which can make
the ifunc resolver crash at program startup. This attribute
was not introduced until GCC 7 and Clang 13, so ifunc won't
be used with prior versions of these compilers.

This bug was brought to our attention by:

    https://bugs.gentoo.org/925415

And was reported to upstream GCC by:

    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=11411

46c3e113d8 CMake: Warn if gettext tools and pre-created .gmo files are missing.
It's only done with CMake >= 3.20 and if library support
for translation was already found.

5c91b454c2 xz: Change logging level for thread reduction to highest verbosity only.
Now that multi threaded encoding is the default, users do not need to
see a warning message everytime the number of threads is reduced. On
some machines, this could happen very often. It is not unreasonable for
users to need to set double verbose mode to see this kind of
information.

To see these warning messages -vv or --verbose --verbose must be passed
to set xz into the highest possible verbosity mode.

These warnings had caused automated testing frameworks to fail when they
expected no output to stderr.

Thanks to Sebastian Andrzej Siewior for reporting this and for the
initial version of the patch.

a100f9111c Build: Fix Linux Landlock feature test in Autotools and CMake builds.
The previous Linux Landlock feature test assumed that having the
linux/landlock.h header file was enough. The new feature tests also
requires that prctl() and the required Landlock system calls are
supported.

32b0a3ce19 Build: Fix ARM64 CRC32 instruction feature test.
Old versions of Clang reported the unsupported function attribute and
__crc32d() function as warnings instead of errors, so the feature test
passed when it shouldn't have, causing a compile error at build time.
-Werror was added to this feature test to fix this. The change is not
needed for CMake because check_c_source_compiles() also performs
linking and the error is caught then.

Thanks to Sebastian Andrzej Siewior for reporting this.

de4337fd89 xz: Landlock: Fix error message if input file is a directory.
If xz is given a directory, it should look like this:

    $ xz /usr/bin
    xz: /usr/bin: Is a directory, skipping

The Landlock rules didn't allow opening directories for reading:

    $ xz /usr/bin
    xz: /usr/bin: Permission denied

The simplest fix was to allow opening directories for reading.
While it's a bit silly to allow it solely for the error message,
it shouldn't make the sandbox significantly weaker.

The single-file use case (like when called from GNU tar) is
still as strict as possible: all Landlock restrictions are
enabled before (de)compression starts.

1ee716f740 Windows: Update windows/build.bash.
Support for the old MinGW was dropped. Only MinGW-w64 with GCC
is supported now.

The script now supports also cross-compilation from GNU/Linux
(tests are not run). MSYS2 and also the old MSYS 1.0.11 work
for building on Windows. The i686 and x86_64 toolchains must
be in PATH to build both 32-bit and 64-bit versions.

Parallel builds are done if "nproc" from GNU coreutils is available.

MinGW-w64 runtime copyright information file was renamed from
COPYING-Windows.txt to COPYING.MinGW-w64-runtime.txt which
is the filename used by MinGW-w64 itself. Its existence
is now mandatory, it's checked at the beginning of the script.

The file TODO is no longer copied to the package.

b0d1422b60 CMake: Don't assume that -fvisibility=hidden is supported outside Windows.
The original code was good enough for supporting GNU/Linux
and a few others but it wasn't very portable.

CMake doesn't support Solaris Studio's -xldscope=hidden.
If it ever does, things should still work with this commit
as Solaris Studio supports not only its own __global but also
the GNU C __attribute__((visibility("default"))). Support for the
attribute was added in 2007 to Sun Studio 12 compiler version 5.9.

4430e075f7 CMake: Use -O2 instead of -O3 in CMAKE_BUILD_TYPE=Release.
-O3 doesn't seem useful for speed but it makes the code bigger.
CMake makes is difficult for users to simply override the
optimization level: CFLAGS / CMAKE_C_FLAGS aren't helpful because
they go before CMAKE_C_FLAGS_RELEASE. Of course, users can override
CMAKE_C_FLAGS_RELEASE directly but then they have to remember to
add also -DNDEBUG to disable assertions.

This commit changes -O3 to -O2 in CMAKE_C_FLAGS_RELEASE if and only if
CMAKE_C_FLAGS_RELEASE cache variable doesn't already exist. So if
a custom value is passed on the command line (or reconfiguring an
already-configured build), the cache variable won't be modified.
