The following is just my guess; not tested on Linux with x11 terminal.
I can test only on Mac now, but:

$ ./configure --prefix=$HOME --program-suffix='-5' --with-qt ...
$ make

then gnuplot and gnuplot_qt are built in src/, and

$ make install

this will install gnuplot as $HOME/bin/gnuplot-5, and gnuplot_qt as
$HOME/libexec/gnuplot/5.0/gnuplot_qt-5 (they are renamed when installed).
But qt terminal doesn't work:

$ $HOME/bin/gnuplot-5
gnuplot> set term qt
gnuplot> plot sin(x)
Could not start gnuplot_qt with path "$HOME/libexec/gnuplot/5.0/gnuplot_qt"

i.e., gnuplot-5 tries to start gnuplot_qt but in $HOME/libexec there is
gnuplot_qt-5 but not gnuplot_qt (assuming I haven't installed gnuplot
with --prefix=$HOME but without --program-suffix before).

I guess x11 terminal is 'fixed' so that gnuplot_x11-5 (not gnuplot_x11)
is correctly called. But when we run 'make check', gnuplot_x11 is in src/
but gnuplot_x11-5 is not, so 'make check' will create a symlink as
ln gnuplot_x11 gnuplot_x11-5.
