fix(nxp-tools): fix2 create_pbl buildroot build

For some unknown reasons I did miss this '+' which does not make
sense when I submitted the former commit. We all did miss
it during codre reviews, sorry for the confusion. I do not understand
how it happened, late commits -> stupid issues.

Revert and fix: 634c7d81 fix create_pbl buildroot build
