appendShellStringNoError() and psql_scan_set_passthrough() should be in
src/fe_utils/libpgfeutils.a, but they are both new as of v10.  I suppose
you're somehow linking against a 9.6 or earlier version of that
library.  Looking at the link line, -L/usr/local/lib is probably the
source of the problem.  Do you have any idea how it got there?
I don't see an equivalent reference to the --prefix lib directory
when I do this, so it's not that.
