ELF Tool Chain elfcopy is nearly a drop-in replacement for GNU objcopy,
but does not currently support PE output which is needed for building
x86 UEFI bits.
Add a src.conf knob to allow installing it as objcopy and set it by
default for aarch64 only, where we don't have a native binutils.

Rationale: ident(1) is useful out of RCS, lot of scripts are using ident(1) and
failing when base is built WITHOUT_RCS.
This version is:
- fully compatible with RCS 5.7 ident.
- fully compatible with RCS 5.9 ident.
- passes all ident test from GNU RCS 5.9 test suite
This version has support for: svn extension for the Keyword id (double colon and
# before last $)
Différences with GNU RCS ident:
- no long options as found in GNU RCS 5.9 (but not commented there).
- '-V' reports nothing but has been added for compatibility.

pwrite(2) syscalls are wrapped to provide compatibility with pre-7.x
kernels which required padding before the off_t parameter. The
fcntl(2) contains compatibility code to handle kernels before the
struct flock was changed during the 8.x CURRENT development. The
shims were reasonable to allow easier revert to the older kernel at
that time.
Now, two or three major releases later, shims do not serve any
purpose. Such old kernels cannot handle current libc, so revert the
compatibility code.
Make padded syscalls support conditional under the COMPAT6 config
option. For COMPAT32, the syscalls were under COMPAT6 already.
Remove WITHOUT_SYSCALL_COMPAT build option, which only purpose was to
(partially) disable the removed shims.

The "games" distribution being optional made sense when there were more

occupy less than 0.001% of my laptop's small hard drive. Meanwhile every

they they try to install FreeBSD.

Sanitizer (ubsan) and Profile Guided Optimization.
ASan is a fast memory error detector. It can detect the following types
of bugs:
Out-of-bounds accesses to heap, stack and globals
Use-after-free
Use-after-return (to some extent)
Double-free, invalid free
Memory leaks (experimental)
Typical slowdown introduced by AddressSanitizer is 2x.
UBSan is a fast and compatible undefined behavior checker. It enables a
number of undefined behavior checks that have small runtime cost and no
impact on address space layout or ABI.
PLEASE NOTE: the sanitizers still have some rough edges on FreeBSD,
particularly on i386. These will hopefully be smoothed out in the
coming time.

The work in r258233 hardcoded the assumption that tests was the last component
of the tests tree by pushing tests as an explicit prefix for the paths in
BSD.tests.dist and /usr was the prefix for all tests, per BSD.usr.dist and all
of the mtree calls used in Makefile.inc1. This assumption breaks if/when one
provides a custom TESTSBASE "prefix", e.g. TESTSBASE=/mytests .
One thing that r258233 did properly though was remove "/usr/tests" creation
from BSD.usr.dist -- that should have not been there in the first place. That
was an "oops" on my part for the work that was originally committed in r241823

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.
