I can see why you'd want that, but it seems equally problematic to let
pg_basebackup return, when the WAL files haven't been archived yet and
you therefore don't in fact have valid, restorable backup yet. Have you
considered using the --xlog-method=stream option, to include the WAL
files in the backup? That will make your backups somewhat larger, as the
WAL files are included, but in that mode pg_basebackup won't wait for
the archival and the backup will be restorable even if archive_command
is failing.
