I came across this old issue.  Unless I'm missing something, there is no
reason why pg_isolation_regress needs to be linked with libpq at all,
and it works fine without it.  If we removed the libpq link, then it
would work just like pg_regress and could support "make check".

Apparently, -Wl,--as-needed isn't working too well here.
