Fixed evaluation of static call on external contained in a precompilation library.
Fixed part (5).2 of bug#12606: Stepping with Auto Expressions in sample graphical app causes crash

However, I tested this with rev 68773 and the watch expression
{EV_GTK_EXTERNALS}.gtk_min_ver still gives an error for the sample graphical
application, which uses precompiled vision2.  So I don't think this part has
really been fixed.
