b13edec098 Switch C type safety level to 3 (GCC 14 default), and adjust for GCC 14
No conflict because except for %global build_type_safety 0,
the package is still compatibility with GCC 13 (but does not
enforce the type safety levels anymore).

7331757cf1 Strip all extension builder flags except -fexceptions and -fcf-protection
This preserves binary compatibility with the main interpreters
the extensions are built against while removing Fedora's flags
that are not required to be inherited on user built extensions.

4c05f3cfa2 Enable _FORTIFY_SOURCE=3 by default
Make the _FORTIFY_SOURCE flags configurable so that the command line is
not cluttered with _FORTIFY_SOURCE definitions and undefines.  Introduce
a %_fortify_level variable that a package may override by either
undefining or defining to a specific value.

Also bump the default value to 3, to implement the systemwide proposal
for Fedora 38:

04a4350d3e Add conditional support for always including frame pointers
If `%_include_frame_pointers` is defined, add `-fno-omit-frame-pointer`
and `-mno-omit-leaf-frame-pointer` to the compiler flags to ensure frame
pointers are always included.

This is in preparation for

d0970582ad Set -g when building Vala applications
This requires the build system support VALAFLAGS. At least Meson and
Automake do.

Using -g is desired because it allows us to see Vala source files and
line numbers in backtraces when possible, falling back to generated C
code otherwise. Line numbers for generated C are almost always less
useful when debugging crashes.

38fc865990 ELF notes: rework the description of disabling
I changed the definitions in package-notes to not do anything if
%_package_note_file is undefined. The other macros won't work if it is
not defined anyway, so this is quite natural. With this, undefining
%_package_note_file becomes the most comprehensive mechanism to disable
the feature. (Undefining %_package_note_flags still works so backwards
compat is preserved.)

The new mechanism will work once
https://src.fedoraproject.org/rpms/package-notes/pull-request/1 is merged.
But I don't think it is necessary to add a version requirement here, since
we're only providing the docs here.

95f28bd10b Add -Wl,--build-id=sha1 to the default LDFLAGS
This is already the default for ld.bfd, so this is effectively a no-op
for most packages.  However, lld defaults different build-id algorithm
that the RPM build process does not support, so it needs this flag.

This flag can be overriden by setting the %_build_id_flags macro,
which packages could do if they wanted to use a more secure build-id
algorithm.

e345575f97 %set_build_flags: define LT_SYS_LIBRARY_PATH
This config is to let libtool recognize that our 64bit variant of
%_libdir is actually on the standard/default library path, so libtool
doesn't think it has to be hard-wired as RPATH.  This is proper solution
for libtool RPATH issues described in:

  https://docs.fedoraproject.org/en-US/packaging-guidelines/#_removing_rpath

The libtool script/macros (new enough, v2.4.6+) honor this variable when
it isn't possible to detect the system-wide default library path.  It is
e.g. able to parse /etc/ld.so.* configuration, but there's no info about
/usr/lib64 on Fedora.

So to not force everybody to do:

   %configure LT_SYS_LIBRARY_PATH=...

... rather set this system-wide.  This is low-risk change since
older libtool scripts don't use this variable, and really no other
tools should.
