At the moment piglit needs a copy of the test _source_ around, because
it parses the .m files looking for >>ASSERTION to know how many subtests
each executable contains. With this patch we can instead do:

datura:~/git/xts% xts5/Xlib4/*/XChangeWindowAttributes q
46

Sorry for the ad-hoc extern, but there's not a header for that
declaration already. The code seems to also have a memory of a "reduced
space" build where all the tests are linked into one giant binary; we
don't support building that anyway, but this change would assuredly
break it too.
