If ru_maxrss is in KB in all OSes other than macOS, then we can just
check $host_os in configure and set a macro in config.h indicating
that ru_maxrss need be divided by 1024.

But in manpage for Solaris:
https://docs.oracle.com/cd/E86824_01/html/E54766/getrusage-3c.html

  ru_maxrss
  The maximum resident set size. Size is given in pages (the size of a page, in bytes,
  is given by the getpagesize(3C) function). See the NOTES section of this page.

  Notes
  The ru_maxrss, ru_ixrss, ru_idrss, and ru_isrss members of the rusage structure are
  set to 0 in this implementation.

Is there anyone who can confirm that ru_maxrss is set to zero?
If it is always zero, then we need not bother with page to KB conversion.
