svn commit: r338474 - head/stand

[Warner Losh]

Author: imp
Date: Wed Sep  5 20:02:23 2018
New Revision: 338474
URL: https://svnweb.freebsd.org/changeset/base/338474

Log:
  Be a little conservative about when to force size optimizations.
  
  Reports have come in that there's issue with powerpc and sparc64 since
  we've switched to using -Oz / -Os. We don't strictly need them for
  !x86, so be conservative about when we enable them.
