Subject: egl: add glvnd symbols check
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=c78d2d98409200f0b40d2e7bb7d143afbf1f0895;hp=ba18b968e8745119f66f293a9366c6708c4ed3b8

egl: add glvnd symbols check

According to the spec [1], `__egl_Main` is the only symbol that needs to
be exported. We don't want applications directly linking against
libEGL_mesa.so (apps should always go through libEGL.so, regardless of
who is providing it), so we shouldn't export any other symbols either.

    (this header is the closest there is to a spec)
