You have basically two options:

a) Don't include the WAL files with the base backup.

If you are planning to use PITR, you'll have to archive those separately anyway.
So why include them in the base backup?

b) Use -X f and "set wal_keep_segments" high enough that the WAL files are not deleted.

Yes, namely that WAL files get deleted/recycled from pg_xlog when they are no longer needed.
If your backup takes too long, the earliest WAL files that are needed for recovery to a
consistent state will be gone when the backup is done.
