The issue is the change I made to the ARM BSP to correctly handle section
numbering and TOC. This changed the depth the source builds from and that has
changed the relative path to the BBB P2 debug connector image. HTML does not
generate an error however PDF does. I will push the fix.

I will also push a change to the pdflatex build that sets the TEXINPUTS env
variable to include some sphinx latex support that was being silently ignored.
