libctf: workaround automake bug with conditional info pages
It looks like automake makes assumptions about its ability to build info pages based on the GNU standard behavior of shipping info pages with the distributions. So even though the info pages were conditionalized, and automake disabled some of the targets, it was still creeping in by way of unconditional INFO_DEPS settings. We can workaround this by adding a stub target for the info page when building info pages are disabled. This tricks automake into disabling its own extended generation target. I'll follow up with the automake folks to see what they think.
