Revert "glsl: Refuse to link GLSL 1.40+ shaders that would use fixed function."
This reverts commit 4ec449a6ed1d2cea3bf83d6518b3b352ce5daceb.
I meant to not push this one. Review found that a link error is not
mandated: it should link, but you get undefined rendering if you rely
on a missing stage.
page 42/55 section 2.11 "Vertex Shaders":
"If the program object has no vertex shader, or no program object
is currently in use, the results of vertex shader execution are
undefined."
(and similar for page 160/173 section 3.9 "Fragment Shaders" for FS,
and page 45/58 section 2.11.2 "Program Objects" for program being 0)
It turns out the commit was broken anyway, because it was missing a
"goto done", so linkstatus got smashed back to true later and the
error just showed up as a warning in the infolog.
