I looked at this a bit more and found that on Linux, the dynamic
loader is documented to search "rpath" before LD_LIBRARY_PATH;
so had we not specified an rpath when building the psql executable,
pg_regress would have worked as intended.  Sounds like BSD is the same.

Now, not specifying rpath seems like a sure loss for every context
except "make check" with an uninstalled version.  So I'm afraid we have
to live with it.  It might be worthwhile for build-farm builds to use
"configure --disable-rpath", if they want to "make check" without
installing first.
