error: undefined reference to 'ffsll'

[leleliu008]

int ffsll(long long int i); function is not in Android-NDK. so we should check if hasffsll in configure script.

#ifndef HAVE_FFSLL
    #define ffsll(x) lrzip_ffsll(x)
#endif

static int lrzip_ffsll(long long i) {
    if (0 == i) return 0;
    int bit;
    for (bit = 1; !(i & 1); ++bit)
        i >>= 1;
    return bit;
}

this problem has been fixed already, I used lrzip-0.631
