How about something like this:

# This file is parsed many times, so the string may get added multiple
# times. Also, the prefix needs to be different based on whether
# CONFIG_SPL_BUILD is defined or not. 'filter-out' the existing entry
# before adding the correct one.

filter-out helps to avoid both problems.
