I probably do not know enough to write it well enough myself - mainly
because I am unsure of your intended audience. If it is debian you may only
be interested in porting between different linux versions - which could be
'tricky' in itself.
However, I see you mention 'OpenBSD', and linuxisms. Why not 'POSIX'? Why
not compiler differences (even different versions of gcc have key
differences). As aixtools I try to package (port) open-source to AIX and
the main problems I run into is that for literally one function in a
complex library (e.g., glib) that has nearly impossible demands to meet on
a non-linux platform (i.e., they 'demand' a feature of gcc for packaging
the complete library) using it's legacy compiler - means the package will
likely never be ported or maintained outside of a linux environment - where
gcc is the 'native' compiler, plus glibc (which is different that POSIX
libc) - aka run-time environments.
As I said above, I am probably not the right person to right this - alone
at least. But I do feel some 'guidance' about how to design and develop
with portability in mind. Every dependency added (because it was there)
adds a potential for a security breach via those dependencies (and their
respective dependencies). Portability is not 'for free' - it requires
planning and documentation.
While it might be a 'hassle' your code might be mich more secure, and
certainly easier to port, if you look at the (one) function you are using
from a someone else's library - and embed it in your code.
That is, rather than just a list of soem areas that affect portability -
think about a high-level description of the common causes of 'lack of
portability' and how to test and/or code for exposure to these common
causes. Sometimes it is 'as simple' as finding (multiple) someone(s) with
another platform who just tries to package (or just make install) it.
Also test that 'make DESTDIR=/some/where/else install' works well.
p.s. - Very glad to see you are opening the discussion!

This page seems it will be useful; I will add some bits to it.
