When sphinx-build is invoked without the -d command line switch, the
default path to the directory in which cached environment and doctree
files are placed is OUTPUTDIR/.doctrees. This causes the contents of
such cache directories to needlessly be included in BIND release
directories. Avoid that by employing the -d command line switch to make
each sphinx-build process use a cache directory outside the output
directory. Make sure these cache directories are separate from each
other as well, to prevent multiple sphinx-build processes running in
parallel from interfering with each other.
In order to prevent documentation building issues from being glossed
over, pass the -W command line switch to all sphinx-build invocations.
This causes the latter to return with a non-zero exit code whenever any
Sphinx warnings are triggered.
(cherry picked from commit 51479ed9a3)
Commit b580eb2fb3 inadvertently caused the
man pages for symlinked BIND tools (named-compilezone, tsig-keygen) to
no longer be installed by "make install". Fix by restoring the commands
which ensure that.
Commit b580eb2fb3 inadvertently caused
dnstap-related man pages to be installed unconditionally. Ensure they
are only installed for dnstap-enabled builds.
