>Description:
pkgsrc/x11/gtk3 build fails with a lot of "undefined reference to `epoxy_has_egl_extension'"

On macppc (and maybe on other archs except amd64, i386, evbarm and evbppc), /usr/X11R7/lib/libepoxy.so has no EGL extensions, and needs pkgsrc/graphics/libepoxy instead. But, configure of x11/gtk3 detects /usr/X11R7/lib/libepoxy.so via x11-links and does not link /usr/pkg/lib/libepoxy.so which has EGL extensions.

A build log of x11/gtk3 is available at
https://d4407.kankyo-u.ac.jp/~nakaji/NetBSD/macppc/gtk3.log

Thanks.
>How-To-Repeat:
make -C /usr/pkgsrc/x11/gtk3 all
