Rather than forcing everyone to provide their own definition of the symbol

This resolved the build of the standalone pipe-drivers, as it provides a
default symbol which was missing previously.

Is program/ really the right place for this? (maybe main/ instead?)
Hmm main/ might be better indeed. If there are any recommendations
about the name I'll gladly take it :)

From a quick look I cannot find a suitable alternative for
__attribute__((weak)) for MSVC. Would you know any of the top of your
head or should I just wrap the attribute in ifndef _MSC_VER and leave
the rest ? If I drop the weak_errors.c hunk from the SCons here, and
replace tests/common.c with it things should just work.
I'd have to do some digging to answer the MSVC question.
I guess I'm not totally clear on the background of what's going on here,
but let me make a suggestion.
The comment in src/gallium/state_trackers/xa/xa_tracker.c says that it's
called by NIR, but I can't find any calls to _mesa_error_no_memory() in
src/glsl/nir/. I guess the actual calls are in the src/glsl/ code, right?
I ran into a similar thing in the glapi code where I wanted to call some
core Mesa function, but didn't want a dependency of that nature.
The solution was to use a callback function.
So, could we add a function to the glsl/nir code which registers an
out-of-memory callback function? The glsl/nir code could have a default
fprintf(stderr) fallback. But Mesa would register a callback that
actually calls _mesa_error() to record the error.
That seems cleaner than using a compiler/linker work-around.
