A reduced test:
int main()
{
    int romfsb_size = 1;
    int nblocks_good_1 = __builtin_constant_p( 1 ) ?
        ({ 2; })
        : 3;
    int nblocks_good_2 = __builtin_constant_p( romfsb_size ) ?
        2
        : 3;
    int nblocks_bad    = __builtin_constant_p( romfsb_size ) ?
        ({ 2; })
        : 3;
    return 0;
}

A bad case: using a variable in __builtin_constant_p and computed
value ({ 2; }) together
