libiodbc opportunistically links with at least gtk2

[ryandesign (Ryan Carsten Schmidt)]

In r97345 I added a libpng dependency to libiodbc, but apparently it still needs dependencies on other ports—at least gtk2:

$ port provides /opt/local/bin/iodbcadm-gtk
/opt/local/bin/iodbcadm-gtk is provided by: libiodbc

It looks like it only opportunistically links against gtk2 +x11, where as +no_x11 and/or +quartz actually fails to be found entirely.

[nerdling (Jeremy Lavergne)]

gtk2 +x11 required in r98363.

libiodbc has a compile option --disable-gui, in that case gtk2 and x11 are not needed. I think it should be solved with a "gui" variant, so user don't have to install x11 and gtk2 if they don't need gui.

Made a new issue for this: #38433
