This is caused by the PACKAGE=foo assignment in foo/Makefile.inc which
overrides the default PACKAGE?=tests in bsd.test.mk.
To fix this, instead use PACKAGE?=foo in foo/Makefile.inc and set
PACKAGE=tests in foo/tests/Makefile.

__FreeBSD_version is recorded in *crt1.o and crti.o via crtbrand.o. Add
an explicit dependency to pick up __FreeBSD_version bumps.
Additional changes are required to fully plumb *crt1.o dependencies
through the build.

Headers from src/include were in the runtime-dev package but
subdirectories of src/include ended up in utilities-dev by default.
Neither package is a good choice - the headers in src/include are not
useful without the libraries contained in clibs-dev.
This moves the standard C headers to clibs-dev (C++ headers are already
in this package). While working on this, I found that various clang
libraries and headers were also bundled into utilities-dev by default
so these are also moved to clang-dev.
I also added a FreeBSD-build-essential meta package to make it simple to
install all the toolchain parts.

The right unwinding stop indicator should be CFI-undefined PC.
https://dwarfstd.org/doc/Dwarf3.pdf - page 118:
If a Return Address register is defined in the virtual unwind table,
and its rule is undefined (for example, by DW_CFA_undefined), then
there is no return address and no call address, and the virtual
unwind of stack activations is complete.
The hack localizing _start1 symbol removed.

__FBSDID() places the provided string in the output object's .comment
section. However, with the transition to Git $FreeBSD$ is no longer
expanded and so we emitted a literal $FreeBSD$.
$FreeBSD$ will be addressed in a holistic manner in the future, but at
least avoid embedding it into everything linked on FreeBSD (via csu).

This adds two new options WITH_ASAN/WITH_UBSAN that can be set to
enable instrumentation of all binaries with AddressSanitizer and/or
UndefinedBehaviourSanitizer. This current patch is almost sufficient
to get a complete buildworld with sanitizer instrumentation but in
order to actually build and boot a system it depends on a few more
follow-up commits.

The ELF notes compiled in C were placed in a section with the wrong type
(SHT_PROGBITS instead of SHT_NOTE). Previously, sed was used on the
generated assembly to rewrite the section type. Instead, write the notes
in assembly which permits setting the correct section type directly.
While here, move inline assembly entry points out of C and into assembly
for aarch64, arm, and riscv.

Summary:
In r209294 kib added -fno-asynchronous-unwind-tables to the compile
flags for the GNU C startup components. This was done to work around a
BFD ld assertion, "no .eh_frame_hdr table will be created", which is
produced because of the layout of the startup objects.
Add the same flag to lib/csu too, for the same reason. And similarly to
r209294, also add -fno-omit-frame-pointer.
This is primarily meant to quickly MFC to stable/11, so it can end up in
the 11.4 release, as a fix for https://bugs.freebsd.org/246322.

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.
This is currently disabled until __dso_handle support is added.

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and

I'm setting WARNS?=0 for secure/. It seems secure/ includes the

Most of the code there is contributed anyway.
- It is opt-out for now so as to give it maximum testing, but it may be
turned opt-in for stable branches depending on the consensus. You
can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
It is harmless to steal the knob as SSP symbols have been provided
by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
(sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
libc will be automatically downgraded to -fstack-protector because it
breaks rtld otherwise.
- This option is unavailable on ia64.
Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.
