Not really.  Comparing the provided libc.log with a successful build, 
the relevant errors seems to be:

I've no idea what that error message is trying to say, but the missing 
index seems to be a consequence of it.

It's kind of odd that the stuff under @ifinfo is being processed at all 
for making a PDF.

I did touch this file in 44e5c14e.  It might be worth checking if 
reverting that makes a difference.
