New Revision: 198203
URL: http://svn.freebsd.org/changeset/base/198203

Log:
  Change the load base to below 2GB so PIE binaries work including when
  compiled to use the Medium/Low code model, which we currently default
  to for the userland. GNU/Linux has moved their default to Medium/Middle
  some time ago, which probably explains why the current GNU ld(1) uses
  a base in the range between 32 and 44 bits instead.
