 You can simply change

SED_CONFIG_EXP="s/^\(# \)\{0,1\}\(\(CONFIG\|BR2\)_[a-zA-Z0-9_]*\)[= ].*/\2/p"

so the script works both for buildroot and for traditional Kconfig.

 I think it's worth to upstream this change to buildroot. Which means adding a
patch to the patches directory to make that change.
