[Konstantin Belousov]

Author: kib
Date: Sun Nov  4 19:11:32 2018
New Revision: 340136
URL: https://svnweb.freebsd.org/changeset/base/340136

Log:
  Move the fixed base for PIE loading on arm.
  
  Existing base causes conflicts for direct execution of ld-elf.so.1
  because default linking base for non-PIE binaries is 0x10000.
