Running make gettext will override any value provided in SPHINXOPTS. The Makefile currently has gettext: SPHINXOPTS += -d build/doctrees-gettext since fb0cf7d (edited with 315a933) and it doesn't append such value, but replaces instead.
Steps to reproduce (from Doc folder):
make gettext # See '-d build/doctrees-gettext' added to command line
make gettext SPHINXOPTS='-q' # See '-q' ignored, and '-d build/doctrees-gettext' added to command line
