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.
bfd/ChangeLog
* elfxx-mips.c(_bfd_mips_elf_modify_segment_map): Deleted hard coding of
PT_DYNAMIC segment flags.
ld/testsuite/ChangeLog
* ld-mips-elf/pic-and-nonpic-3a.sd: Check DYNAMIC segment flags.
