old-cross-binutils/bfd/ChangeLog
Jack Carter 5db3e65d39 The PT_DYNAMIC segment was being hard coded to have read, write, and 
execute permission regardless of the underlying PT_LOAD segment permissions.
Deleting this code allows the default linker behavior which is to set the
dynamic segment to the same permissions as the sections that make it up.

This change alters one existing test case to check the segment flags for
PT_DYNAMIC.

        PT_DYNAMIC segment flags.
