Do libwebkitgtk based browsers work on ppc64?

Hello everyone,

The topic of web browsers that (don't) work in powerpc/ppc64 port has come up a
few times on the mailing list.

>From the browsers packaged in Debian, Netsurf works ok for me, but there are
many things one would expect from a modern browser that it cannot do.

Do any of the browsers based on libwebkitgtk (like Epiphany or Surf from
suckless) work on ppc64? When trying to run Epiphany I get several libEGL and
GLib warnings and a non-functional browser window. Is this an issue with my
configuration, or are these browsers known not to work?

Many thanks,
João
