Oops, I thought it had been there for a while, but maybe not really that long.

Okay, so your sysconf doesn't support this attribute and neither does
getconf, so it's returning an out-of-band value and configure complains
that it's out of range.  I added C-side sanitization of the return value
so that it will use the defaults if auto-detection fails.  Should I also
redirect stderr so that getconf doesn't print the error (when called by
conftest)?
