include symbols in compiled device trees

enables use of overlays which heavily rely on labels (stripped without
symbols) at the cost of slightly bigger size of output files. PLD likely
won't ever be used on devices for which size could make any difference
while having possibility to use overlays is very much practical

pass in environment instead of make opt to preserve appended -Wno*
