Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

Prior to this commit, primes(6) relied solely on sieving with primes up
to 65537, with the effect that composite numbers which are the product
of two non-16-bit primes would be incorrectly identified as prime. For
example,
# primes 1099511627800 1099511627820
would output
1099511627803
1099511627807
1099511627813
when in fact only the first of those values is prime.
This commit adds strong pseudoprime tests to validate the candidates
which pass the initial sieving stage, using bases of 2, 3, 5, 7, 11,
13, 17, 19, and 23. Thanks to papers from C. Pomerance, J.L. Selfridge,
and S.S. Wagstaff, Jr.; G. Jaeschke; and Y. Jiang and Y. Deng, we know
that the smallest value which passes these tests is 3825123056546413051.
At present we do not know how many strong pseudoprime tests are required
to prove primality for values larger than 3825123056546413050, so we
force primes(6) to stop at that point.

Check if large factor is prime before applying Pollard's algorithm;
fixes "factor 2147483647111311". Increase base if p-1 algorithm
reaches 1; fixes "factor 99999999999991".

Problem rediscovered by an attempt to factor my phone number.
A few other incidental fixes: correct a couple of factually incorrect

Use '0' for base rather than 10 to allow for more flexible input bases.
Inspired by changes in PR 7402, but mostly redone by me to get past

EOF? The getopt(3) manpage clearly states that the return value is *-1*,
not EOF! Besides, getopt(3) isn't reading from a file. :)

and do this in two stages since it's just not worth it for this collection,
and I've got directory renames to deal with that way. Bleah.
