It should work fine as is. The emerge output does not show where PYTHON_SINGLE_TARGET is set for app-text/asciidoc, but that would be a local configuration problem anyway. I suggest looking in /etc/portage/profile/package.use.
You are right. I completely forgot about package.use. Incorrect asciidoc configuration was there. Thank you for your help.
