It's indeed related to my configuration:
I have GNU libiconv installed from the OpenBSD package repository in /usr/local.
I have GNU gettext installed from source in $HOME.
Therefore I use this configure command:
../configure --prefix=$HOME \
CPPFLAGS="-I$HOME/include -I/usr/local/include -Wall" \
LDFLAGS="-L$HOME/lib -L/usr/local/lib"
On other OSes, this is sufficient for the GNU gettext.m4 macros
to set LIBINTL="-I$HOME/lib -lintl -Wl,-rpath,$HOME/lib", and things
work fine.
On OpenBSD, config.status sets
LIBINTL="/home/bruno/lib/libintl.so.12.3 /usr/local/lib/libiconv.so.7.1
-Wl,-rpath,/usr/local/lib"
Somehow the directory /home/bruno/lib is missing from rpath.
Therefore I have set the environment variable LD_LIBRARY_PATH=/home/bruno/lib.
Now,
$ readelf -d src/printenv

You can see that the information where to find libintl.so.12.3 is not
present in the executable. Therefore the LD_LIBRARY_PATH variable
is necessary.
Now, "env -i ... ../src/printenv" clears the environment, including
the LD_LIBRARY_PATH variable.
Is removing LD_LIBRARY_PATH along with all other environment variables
causing the trouble? Yes.
Is my environment misconfigured? I don't think so. Everything else is
working fine.
Should LIBINTL better be set to
LIBINTL="/home/bruno/lib/libintl.so.12.3 /usr/local/lib/libiconv.so.7.1
-Wl,-rpath,/home/bruno/lib -Wl,-rpath,/usr/local/lib" ?
If I do this and rebuild, src/printenv no longer relies on LD_LIBRARY_PATH,
and "make check" passes.
Should LIBINTL better be set to
LIBINTL="/home/bruno/lib/libintl.so.12.3 /usr/local/lib/libiconv.so.7.1
-Wl,-rpath,/home/bruno/lib:/usr/local/lib" ?
This works too, likewise.
Why does the configuration not set LIBINTL to contain both directories in rpath?
Becaus /usr/local/lib also contains a libintl, but of an older version
(libintl.so.8.0); that's not the one I want to use.
