That would also work, but it's generally best not to mix
'depends on' and 'select' for the same symbol. Changing
all three 'select P2SB' to 'depends on P2SB', or removing
the prompt to turn P2SB itself into a hidden symbol is
probably a good follow-up patch, but I'd keep that separate
from the regression fix.
