automake: don't enable -Wl,--no-undefined on OpenBSD

OpenBSD does not have DT_NEEDED entries for libc by design,
over concerns how the symbols would be referenced after
changing the major version of the library.

So avoid -no-undefined checks on OpenBSD as they will fail.

v2: don't include the -no-undefined libtool option in the variable
    and change -Wl,--no-undefined references in Automake.inc as well.

glapi: Enable ES compatibility mode

Ages ago Chia-I added an ES compatibility flag to several of the various
generator scripts.  The intention was to bridge differences between ES
and desktop in Mesa builds without ES.  It doesn't appear that it has
ever been used.  Recent changes to static_dispatch status of several ES1
functions caused problems in desktop-only, non-shared-glapi builds.
Enabling the ES compatibility mode appears to fix these build problems.

This is kind of a duct tape solution to this problem.  As I mentioned in
the cover letter for the series that triggered the build problem, I
would like to make some major changes to the generator architecture and
the XML.  The whole point of the proposed architecture changes is to
better handle the differences between desktop GL and ES.  I think duct
tape is okay for now.

C89 has a fairly short minimum-maximum string length.  To support

mapi: Hack around glGetInternalformativ not being hidden in GLES

This is hella ugly.  The same-named function in desktop OpenGL is
hidden, but it needs to be exposed by libGLESv2 for OpenGL ES 3.0.
There's no way to express in the XML that a function should be be hidden
in one API but exposed in another.

This won't affect any change now, but it will prevent a regression in a
later patch.
