Comment (by MarcusCalhoun-Lopez):

 As far as I can tell, this problem is:
 * webkit2-gtk
 [https://trac.webkit.org/browser/webkit/releases/WebKitGTK/webkit-2.14.2/Source/WebKit2/PlatformGTK.cmake#L916
 runs g-ir-scanner] with {{{-L${prefix}/lib}}}
 * Not surprisingly, g-ir-scanner passes {{{-L...}}}
 [https://gitlab.gnome.org/GNOME/gobject-
 introspection/blob/master/giscanner/ccompiler.py#L154 to the compiler]
 * Somewhat surprisingly, g-ir-scanner also [https://gitlab.gnome.org/GNOME
 /gobject-introspection/blob/master/giscanner/ccompiler.py#L164 appends the
 directory to DYLD_LIBRARY_PATH]
 * The use of DYLD_LIBRARY_PATH is a somewhat
 [https://gitlab.gnome.org/GNOME/gobject-
 introspection/commit/3a5c4dc8d776ad2bfe18e47b2ee940cb9f1fc5d4 recent
 addition], and the developers seem to believe it be important

 I would humbly submit that a solution might be to replace
 DYLD_LIBRARY_PATH with DYLD_FALLBACK_LIBRARY_PATH in gobject-
 introspection.
