Can we make that more readable:

BUILD_OPTIMIZATION = "${@'-O -g -feliminate-unused-debug-types -fno-omit-frame-pointer' if d.getVar('DEBUG_BUILD') == '1' else '-O2'} -pipe"

Should probably do the same for SELECTED_OPTIMIZATION while at it:

SELECTED_OPTIMIZATION = "${@d.getVar('DEBUG_OPTIMIZATION' if d.getVar('DEBUG_BUILD') == '1' else 'FULL_OPTIMIZATION')}"
