For example, from the referenced PR [1]:
$ mkdir /tmp/lib/ /tmp/libexec
$ touch /tmp/lib/foo.so
$ install -lrs /tmp/lib/foo.so /tmp/libexec/
The common path identification bits terminate src at /tmp/lib/ and the
destination at /tmp/libe. The subsequent backtracking is then incorrect, as
it traverses the destination and backtraces exactly one level while eating
the 'libexec' because it was previously (falsely) identified as common with
'lib'.
The obvious fix would be to make sure we've actually terminated just after
directory separators and rewind a character if we haven't. In the above
example, we would end up rewinding to /tmp/ and subsequently doing the right
thing.
Test case added.

I need these tools in order to install the crossbuilt FreeBSD and create a
disk image. Linux does not have a st_flags in struct stat so unfortunately
I need a bunch of ugly ifdefs. The resulting binaries allow me to
sucessfully install a MIPS64 world and create a disk-image that boots.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
If stat continues to fail with ENOENT and mkdir with EEXIST the code wont
finish. In particular this can show up when the target path follows through
a symlink to a non-existent directory.

The additional testcases use absolute paths for sources and targets,
as the other testcase which tested `-l sr` used flat relative paths in
the same directory.
Please note that these testcases do not test `-l a` -- that's already
addressed in the battery of tests.

Unfortunately kyua does not omit the path mismatch on failure, so it must be coded
into the error message.
Cache the values, run the test(1) call, then print out the values in an atf_fail
call to emit the required diagnostics to debug why things are failing.

It was unlinking the target even though it uses rename(2) which already
effectively does that. -S is intended to not unlink(2) the target first.

With both of these flags, the backup was created via rename(dest, backup)
followed by rename(tmp, dest). This left the destination file missing
for a moment which contradicts the point of -S.
This fixes a race with installworld where PRECIOUSPROG and PRECIOUSLIB
files (which use -S for installation) would briefly be missing. In the
case of installing rtld with parallel installworld it could render an
error due to not having rtld present to run install/cp in another
process.

This should fix the build on older stable/10, since install is a bootstrap
tool.
Pending a decision how to fix this properly, revert utimensat usage. Copies
with the -p option will again appear older than the original almost always,
but -p is not commonly used.
The main problem was bitrot after elftoolchain being swapped in for the
GNU toolchain.
This also reworks how the list of 'host allowed' libraries is determined
to only allow INTERNALLIBs, which is needed for libelftc to come in.
For usr.bin/readelf use the same hack, as libelf and libdward, to bring in
the needed sys/ headers for host builds. This has not yet been a problem due
to readelf not being built as a host tool in buildworld. This is possible
in the meta build though when building the toolchain.

In case the target of install is a dead symlink, install(1) used to not
consider it as "existing" because of the usage of stat(2) instead of
lstat(2). meaning the old file (the symlink) is not removed before the new
file is created. The symlink is being followed and the new file becoming the
target of the symlink instead of the target of install(1)

The bootstrap-tools are supposed to be host tools, which in most cases, use
host headers and libraries. As such, directly including the src tree's headers
for libmd here causes the need to link libmd in since it will be built with
the new symbols (which /usr/lib/libmd.so) won't have unless it is new enough.
During the target build in buildworld the target headers are staged into
WORLDTMP and used via --sysroot, allowing the target xinstall to be built with
the new/target libmd.
The .PATH here was also not doing anything since xinstall does not use libmd
source files.

Since the code stats and mkdirs in 2 separate steps, it is possible that
the directory will be created in the meantime by something else (e.g.
concurrent install).[1]
While here alter the code to properly report stat failure, previously it
would always claim it was mkdir which failed.
