commit 90fc4832a392f60d2da2f5684d8d20ac8d91cebd

    bn/asm/ppc-mont.pl: signal no-op in 32-bit bit build.
    
    The bug was introduced in 80d27cdb84985c697f8fabb7649abf1f54714d13,
    one too many instructions was removed. It went unnoticed, because
    new subroutine introduced in previous commit is called in real-life
    RSA/DSA/DH cases, while original code is called only in rare tests.
    The bug was caught in test_fuzz.
