New Revision: 217395
URL: http://svn.freebsd.org/changeset/base/217395
Log:
On PowerPC64, linker emits a fake object into each linked object,
'linker stubs'. Add .note.GNU-stack for the stubs objects. Without this,
final binary will have RWE mode for PT_GNU_STACK regardless of the
actual requirements.
