    i386: fix -march=3Damd crash

    It started with g:3e2ae3ee285a57455d5a23bd352a68c289130186 where
    new entry was added to processor_alias_table after generic node:

    +  {"amdfam19h", PROCESSOR_GENERIC, CPU_GENERIC, 0,
    +    M_CPU_TYPE (AMDFAM19H), P_NONE},

    and then the following is violated:

    /* NB: processor_alias_table stops at the "generic" entry.  */
