I tested with my script which has the following code

BR2_RASPAUDIO_PAACCESS="$( sed -r -e '/^BR2_RASPAUDIO_PAACCESS="(.*)"$/!d;'    \
                         -e 's//\1/;'                                           \
                         "${BUILDROOT_CONFIG}"                                  \
                )"


which is adapted from the mkusers script... and it failed silently.

I am not sure how to deal with the situation. I don't really see a better
way, but silently failing in a case where I copied what is done in mainline
seems a bad idea...
