[waffle] [PATCH] egl: resolve build issue with pre EGL 1.5 headers

[Emil Velikov]

In some cases (like building on Android) the headers might not have the
1.5 definitions, leading to a build failures like the one in github
issue #41.

Since the ABI is baked in stone, add a local define to resolve that.
