here is the current status of TeX Live 2016 builds on OpenBSD at Utah:

The problem report at
http://www.tug.org/pipermail/tex-live/2007-January/011870.html
refers to build failures on OpenBSD due to missing symbols from the
-lpthread library. That library IS available on OpenBSD, but it make
take a package installation to put it onto your system. The problem
is that the contents of -lpthread are in -lc on many flavors of Unix,
so there are at least three erroneous configure.in scripts in the TeX
Live tree that fail to test for the need for a separate -lpthread
option.

Both wget and xz are available in the OpenBSD package systems back to
at least OpenBSD 4.9, so I don't believe that they pose any serious
issue.
The GNU config.guess script works fine all versions from 4.9 to 5.9,
with output like this on my various OpenBSD systems:
i386-unknown-openbsd4.9
...
amd64-unknown-openbsd5.9
Although developers with single-user systems often like to ride the
bleeding edge of O/S releases, larger sites often have constraints
imposed by other critical software or hardware that prevent easy
upgrades to newer O/S releases (e.g., at our site, we cannot upgrade
our thousands of users with thin clients from CentOS 6 to CentOS 7,
because the kernel modules needed to support our Oracle Sun Ray
stations are not yet available on CentOS 7: moving to alternate thin
clients is economically infeasible when about 400 of them would have
to be bought, at a cost of US$250 to US$500 each).
As the above Web site notes, it is often possible to run software from
older O/S releases on newer ones in the same architecture and O/S
family, subject to availability of shared libraries and suitable
kernel symbols.
As an experiment for OpenBSD, I just copied all of the OpenBSD binary
directories to OpenBSD 5.9 (the latest one, barely two weeks since its
official release). Here is what I found:
% foreach f ( x86_64-openbsd-5?/tex)
echo $f ; ./$f --version
end
x86_64-openbsd-54/tex
./x86_64-openbsd-54/tex: can't load library 'libc.so.69.0'
x86_64-openbsd-55/tex
./x86_64-openbsd-55/tex: can't load library 'libpthread.so.18.0'
x86_64-openbsd-56/tex
./x86_64-openbsd-56/tex: can't load library 'libpthread.so.18.0'
x86_64-openbsd-57/tex
./x86_64-openbsd-57/tex: can't load library 'libc.so.78.1'
x86_64-openbsd-58/tex
./x86_64-openbsd-58/tex: can't load library 'libc.so.83.0'
x86_64-openbsd-59/tex

It therefore looks to me like we need to have separate binaries for
each OpenBSD release. Here are their disk space requirements:
% du -sh x86_64-openbsd*
150M x86_64-openbsd-54
150M x86_64-openbsd-55
152M x86_64-openbsd-56
152M x86_64-openbsd-57
152M x86_64-openbsd-58
157M x86_64-openbsd-59
Given that the TeX Live YYYY DVD has been chock full for years, we are
unlikely to have the DVD space to hold more than a dozen or so of the
binary directories for the most common platforms.
The rest, however, we can easily supply via Web download, at least for
those end users who have adequate Internet connections. With gzip -9
and xz -9 maximal compression, those directories can be squeezed down
to about a third of their original sizes:
% du -sh *.tar.*
53.4M x86_64-openbsd-59.tar.gz
49.2M x86_64-openbsd-59.tar.xz
If anyone on this list has contact with the OpenBSD folks who built
TeX Live for earlier O/S releases, then we should open a dialog with
them, and help them to get TeX Live 2016 distributions for at least
the last half-dozen O/S versions. I'll be happy to collaborate with
them.
