Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option.

Browse Source 
When enabled, the "unknown function" error is suppressed for EXPLAIN and
a no-op function named "unknown()" is substituted.  This facilitiates using
the command-line shell to analyze queries from applications that contain
many application-defined functions that are not normally available to the
shell.
