[Buildroot] [git commit] libserial: prevent documentation from being build

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=2e0aff3b5cf2f83a3ddd31dfd572b29a8288f6be
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

If docbook2pdf is present on the host, the documentation is built, no
matter all the --disable-doc*
But forcing ac_cv_prog_DOCBOOK2PDF to no tells configure that
docbook2pdf is absent, and thus the documentation is not built.
