svn commit: r364701 - in head: . tools/build

[Warner Losh]

New Revision: 364701
URL: https://svnweb.freebsd.org/changeset/base/364701

Log:
  When copying over the binaries, use '-p' to preserve date/time
  
  Although I can't reproduce it, others are seeing different lex/yacc
  programs always regenerated after my change to copy rather than
  symlink the files. The reported fix is to add '-p' to the copies.
  Since it doesn't hurt, go head and add it, though the reasons for
  this mattering remain at best obscure and poorly articulated.
