Problem with building PDF documentation

[Freddie Chopin]

Hello!

I've tried building the most recent newlib for arm-none-eabi and I 
encountered a problem when building PDF documentation. I guess this problem is 
specific to the very recent version of TEX utils on my system (Arch Linux). I 
attach the log from the console - the part where the generation of libc.pdf 
fails. I also attach libc.log file generated during compilation. Both files 
are compressed, because they are over 100kB

I have a very similar problem with building PDF for binutils (I reported that 
on binutils mailing list). However generated as.pdf file looks OK (I did not 
inspect it very thoroughly), while in the libc.pdf document there is no index 
- there is a chapter for index, but all it has is this:

> Document Index
> (Index is nonexistent)

Here are the versions of relevant tools:

The texlive package I have is 2015.37497-5.

I guess it it also worth noting that I had no trouble building PDF 
documentation for newlib (and binutils) at the end of Semtember (at 28th 
exactly) - I used the most recent newlib sources and the most recent software 
packages (at that time). I tried this again with the same version ( 
f296bb3569839b0217ec1a775165d239877e3548 ) and it fails too, so I guess the 
problem is related to tex version (or some component that is used by tex) that 
I use.

If any more info is needed, just let me know.

FCh
