A Legendre symbol type assignment of the modulo ten primes to the polynomial: Expand[(x-1)*(x+1)*(x-2)*(x+2)*(x-0)]=4 x - 5 x^3 + x^5; c(n) = If[Mod[n, 10] == 1, 1, If[Mod[n, 10] == 9, -1, If[Mod[n, 10] == 3, 2, If[Mod[n, 10] == 7, -2, 0]]]] such that n is a prime[n].

Generalized L functions over polynomials modulo to the primes:
Instead of the x^2-1 roots modulo 4 of primes in the Legendre symbol
you identify each modulo value of the primes to a root
and define the function by that.
Modulo 10 of the primes has values {2,5,1,3,7,9};
assigning the roots of the polynomial:
1->1
9->-1
3->2
7->-2
2,5->0
5 root polynomial defined over modulo 10 in primes:
Expand[(x-1)*(x+1)*(x-2)*(x+2)*x]=4 x - 5 x^3 + x^5;
L[s_] = Product[1/(1 - c[Prime[n]]/Prime[n]), {n, 1, Infinity}];
Table[N[L[n]], {n, 1, 5}]
{1., ComplexInfinity, 1., 0., ComplexInfinity}
