Since you've disabled or enabled at least one algorithm, you need
to do
the following before building:
make depend
Exec'ing the 'make depend' stage returns lots of warnings,
make depend
making depend in crypto...
make[1]: Entering directory
'/usr/local/src/openssl/openssl-1.0.2g/crypto'
makedepend: warning: cryptlib.c (reading

On the distro, stddef.h is available at

/usr/lib64/gcc/x86_64-suse-linux/4.8/include/stddef.h
/usr/lib64/gcc/x86_64-suse-linux/5/include/stddef.h
Reading wiki & reports at openssl, there's confusing, if not
conflicting, advice.
Must use it,
(1) https://wiki.openssl.org/index.php/Compilation_and_Installation
Dependencies
If you are prompted to run make depend, then you must do so.
Its not just for developers who are updating sources. Its required to
update the standard distribution once configuration options change.
In your specific case, it seems that you have disabled a protocol or
cipher or whatever, in other words you have changed the default options.
I guess the "..." in your command means just that you are omitting some
options.
So in such case you need "make depend". What is said in point (1) is
correct.
For instance, if you compile some not-latest OpenSSL with -nossl2 (this
is the current hype), compilation will fail unless you issue "make depend".
Sorry but I don't exactly understand how you are quoting the rest, so I
cannot see exactly what is that you find confusing.
Don't need it
(2) https://wiki.openssl.org/index.php/Compilation_and_Installation
Compilation
After configuring the library, you should run make. If
prompted, there's usually no need to make depend since you are
building from a clean download.

"Obviously this needs fixing but as a workaround: if
you're building from scratch (or after "make clean") it should compile
fine with without doing "make depend".
Re: 'makedepend',
https://en.wikipedia.org/wiki/Makedepend
makedepend was developed as part of MIT's Project Athena. It
was used extensively in building X11 and ancillary packages, but has
since become superseded by the dependency generation facilities of
various compilers, and is now used primarily as a worst-case fallback,
e.g. by depcomp and GNU Automake.
Further, a quick check (https://www.google.com/search?q=makedepend+stddef
) shows that there's a long history (unresolved?) re: not finding the
sys's stddef.h
Digging around some more, I find that virtually the same issue was
raised on openssl-dev in Apr 2015,
https://mta.openssl.org/pipermail/openssl-dev/2015-April/001263.html
[openssl-dev] `make depend`, advised by ./config, fails to find
stddef.h in system/compiler path. old bug (#3566) says don't bother
with `make depend`? true, or another bug?
with no reply at all.
What, then, IS the current need for 'makedepend' in openssl, and what,
exactly, is the correct/recommended usage for its use in an openssl
build?
