Don't add PHDR for objcopy/strip or ld script specifying PHDRS
HPPA64 needs to add a DT_PHDR header for shared libs. That's fine
when linking but shouldn't happen for strip/objcopy. Also PHDR must
come first so there's no need to look at all program headers.
bfd/
* elf64-hppa.c (elf64_hppa_modify_segment_map): Don't add PHDR
for objcopy/strip or when a ld script specifies PHDRS.
ld/
* testsuite/ld-elf/nobits-1.d: Remove xfail for hppa64.
* testsuite/ld-elf/note-1.d: Likewise.
* testsuite/ld-elf/note-2.d: Likewise.
