Provided symbols are revised to match those provided by HP ld.
This fixes startup issues caused by defining __FPU_MODEL,
__libdl_jmp_tbl and __systab.
This change adds the emultempl/hppa64elf.em file. We now always
link against /lib/pa20_64/milli.a on HP-UX.
HP-UX shared libraries have some unresolved symbols. So, we also
need to ignore unresolved symbols in shared libraries.
We adjust TEXT_START_ADDR and SHLIB_TEXT_START_ADDR to match the
values used by HP ld.
The .data section is moved to the start of the data segment.

ld/ChangeLog:
* emulparams/elf64hppa.sh (TEXT_START_ADDR): Revise value to match
HP ld value.
(SHLIB_TEXT_START_ADDR): Likewise.
(EXTRA_EM_FILE): Define.
(OTHER_SYMBOLS): Revise to match symbols provided by HP ld.
* emultempl/hppa64elf.em: New file.
* scripttempl/elf64hppa.sc: Move .data to start of segment.
