arc4random() is slow, but it induces getpid() calls; also saves a
bit on stirring efforts

doesn't test it, so factor out the two places that test it into a
routine and do the refreshing there.  With this, arch4random_buf()
doesn't trigger superfluous calls to getpid() when filling large
buffers.

Someone may have passed a read-only string to putenv() (I'm looking
at you cron!).

standard explicitly disallows passing setenv a name with a '=' in
it but historic BSD behavior is to allow this but to ignore the '='
and anything after it.

PAGE_(SIZE|SHIFT|MASK) defines that evaluate to variables on the
sparc architecture;
ok otto@ tested on my reanimated ss20

on sparc, it expands to something that just plain does not work,
because the page size can be variable.  Sorry we didn't spot this
before.  Backing it all out to allow sparc to build; please find a
different way to fix it.
