Thanks. I'm afraid I don't know anything about libGL :) I know that
the build succeeds with the patch, but I suppose you're asking if it
references other symbols not listed in the ABI.

I found https://www.opengl.org/registry/ABI/ but failed to distill a
list of blessed symbols from that so far. Is there an easy list / tool
to check this?
