I don't think the prime sieving is not a problem, but for each (odd)
prime p, it also computes p^{-1} mod 2^{bits} and floor ( (2^{bits} - 1)
/ p), where "bits" is the size of an uintmax_t. This will break cross
compilation, if uintmax_t is of different size on build and host system,
or if different suffixes (U, UL, ULL) are needed in the generated
primes.h.
