Well the libwpe build script says this:

find_package(EGL REQUIRED)

(https://github.com/WebPlatformForEmbedded/libwpe/blob/master/CMakeLists.txt)

Which suggests that you can't build it without EGL.  You should
investigate whether EGL is simply an option, or whether it's used as a
fundamental part of the rendering.  If it's optional then the Mesa
recipe can build a software GL implementation, if the latter then
you'll need a new browser as software GL is *terrible*.
