Documenting this would make sense. It was not clear to me.

I am still confused.

On one hand, when you say "only on OpenBSD", it reminds me of the problem
that I have seen repeatedly on OpenBSD over the last years (e.g. with
GNU libunistring, when built without --disable-shared): If I have an
older version of GNU libunistring installed (in the directory specified
through --prefix), when building a newer version of GNU libunistring
(i.e. "make && make check") the "make check" part fails because it
apparently uses the older version. Whereas "make && make install && make check"
succeeds. OpenBSD is the only ELF platform on which this 'make install'
before 'make check' is (or used to be) needed.

On the other hand, during "make && make check", none of the libtool
modes --mode=finish and --mode=install is used. Automake does not
generate invocations of "libtool --mode=finish ..." at all, and it
generates invocations of "libtool --mode=install ..." only as part
of 'make install', which is typically the last thing I do in a build
tree. (In the build tree, doing source code modifications and "make"
will regenerate the libraries using "libtool --mode=link ...", but
not invoke "libtool --mode=finish ..." nor "libtool --mode=install ...".)

So, it's not clear to me how your change can have any effect in a
usual build tree as generated by Automake.
