I don't use ox-latex.el and may be missing something, but looking at the
code I think %bib, as described by the docstring of
org-latex-pdf-process, is intended.

When %bib was added in 74da3bc10 (ox-latex: Support arbitrary
bibtex-like program, 2015-07-08), it appears that it was working as
documented.  But with the switch to using format-spec internally in
f6187deca (ox-latex: Small refactor, 2015-09-13), the field was changed
from %bib to %bibtex.  Based on the commit message, I don't think that
was intentional.

Given the situation I described above, I think the options are

  * change %bib to %B (your suggestion) and remove the "bib" part from
    the regexp in org-latex-compile because keeping it around would be
    confusing

  * update the documentation and type in org-latex-pdf-process to use
    %bibtex

  * update the regexp in org-latex-compile to match "bib", not "bibtex"

The last one seems preferable to me, assuming the change from %bib to
%bibtex was an oversight.  What do you think?

Yes, please.
