Actually, for running `make doc` this problem of yours shouldn't
happen at all – if you install the necessary fonts for building the
documentation, these fall-back fonts should never be accessed.

Have you seen chapter 4.2.3, 'Requirements for building
documentation', in the CG?  It lists the following necessary fonts:

  URW++ and TeX Gyre
  Bitstream Vera Sans
  Bitstream Charter
  DejaVu Sans
  DejaVu Serif
  DejaVu Sans Mono
  Linux Libertine O

Have you installed these fonts?
