Yep. The patch needs fixing.
The spec says eglGetProcAddress must work on core EGL functions. dlsym
may work if the vendor chooses to support it.
From the EGL 1.5 spec:
eglGetProcAddress may be queried for all EGL and client API
functions supported by the implementation (whether those functions
are extensions or not, and whether they are supported by the current
client API context or not).
For functions that are queryable with eglGetProcAddress,
implementations may choose to also export those functions statically
from the object libraries implementing those functions. However,
portable clients cannot rely on this behavior.
