FreeBSD has used ELF binaries/libraries for decades, but still has some
support for legacy a.out binaries. Portions of this have been retired
over time, but support remained in ldd, ldconfig, and gprof.
Retire gprof support; if anyone needs to do development on a.out
binaries still they will be best served by installing a full FreeBSD 2.x
or other obsolete version in a jail.
Kernel support for executing a.out binaries is unchnaged.

When exporting a variable we correctly check all the preconditions that
could make setenv(3) fail. Checking the setenv(3) return value seems
redundant, but given that login(1) is critical, it doesn't hurt to have
a post-check.
This change is based on the "Principles of Secure Coding" course by
Matthew Bishop, PhD., which specifically discusses this code in FreeBSD.

Move the include of langinfo.h out of the WITH_ICONV condition block,
since it is not dependent on ICONV. This was correct when nl_langinfo()
had only been called in the WITH_ICONV case, but that is no longer the
case.
Submitted by: yuripv
There was an unprotected use of nl_langinfo() to determine the order of
day vs. month in the generated output.
When building without ICONV support, the order will be: month, day.
yesexpr is an extended regular expression for quite some time now,
use appropriate flag when compiling it.

We know up front how many items we can have in the queue (-B/Bflag), so
pay the cost of those particular allocations early on.
The reduced queue maintenance overhead seemed to yield about an ~8%

This is addressing cases such as fts_read(3) encountering an [EIO]
from fchdir(2) when FTS_NOCHDIR is not set. That would otherwise be
seen as a successful traversal in some of these cases while silently
discarding expected work.
As noted in r264201, fts_read() does not set errno to 0 on a successful
EOF so it needs to be set before calling it. Otherwise we might see
a random error from one of the iterations.
gzip is ignoring most errors and could be improved separately.

r368355 removed the GNU_GREP_COMPAT knob (off by default) and forgot that
bsdgrep may be built/used for bootstrap on some systems.
All base uses should strive to use only POSIX-compliant expressions anyways
and we haven't had libregex by default here up to this point, so just don't
do that if we're bootstrapping.
Note that the resulting binary has the wrong `grep -V` information as it
falsely claims to be GNU compatible, but it is only for bootstrap.
Reported by: GitHub cross-builds via yuripv
This was introduced and then disabled by default primarily to avoid dealing
with bugs in libgnuregex. rS363823 switched to using libregex for it, so
let's just rip the option out now so we can make sure we're getting tested
with libregex via bsdgrep.

of parameters of strgen.sh has been applied to the invocation of this
