teach the BFD tools how to handle NOBTCFI, quite similar to WXNEEDED

Merge post-2.17 but pre-GPLv3 diffs that add support for DT_GNU_HASH
to ld and improve the readelf support:
https://sourceware.org/ml/binutils/2006-07/msg00129.html
https://sourceware.org/ml/binutils/2006-07/msg00181.html

Disable the ld support on mips64, as its ABI requires a symbol
ordering that conflicts with the requirements of DT_GNU_HASH.

Tested on macppc, alpha, and sparc64 to verify operation with all
three ELF word size combos

Make creation of text-relocations a fatal error by default, with -znotext
to permit it and -ztext to reenable the default of forbidding it.

-z wxneeded creates a PHDR PT_OPENBSD_WXNEEDED. This annotation is placed
on a binary by a software builder (ie. packager) to indicate to the kernel
that this software performs W^X violations.

Unbreak binutils on sparc64, hppa (and probably some others).
Jumbo merges are NOT WELCOME. They have to be seperated out and tested.

Introduce -Bsymbolic-functions and related flags. Taken from two
post-binutils 2.17 but pre-GPLv3 commits.
miod@ says now is the time to get this in.

A first attempt at merging our local changes and fixes into the 2.17 codebase.
ld(1) needs a lot more work, as the upstream code evolved significantly since
2.15, mostly due to changes in PIE binaries layout, and we had already
diverged significantly to implement W^X.

branches: 1.1.1;
