Collect .openbsd.syscalls sections into a new PT_OPENBSD_SYSCALLS segment.
This will be used soon to pin system calls to designated call sites.

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

In the linkers, collect objects in section "openbsd.mutable" and place
them into a page-aligned region in the bss, with the right markers for
kernel/ld.so to identify the region and skip making it immutable.
While here, fix readelf/objdump versions to show all of this.
ok miod kettenis

Teach readelf and objdump about the PT_OPENBSD_BOOTDATA section value.
Teach ld to access that and PT_GNU_RELRO in linker scripts.

-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.

Recognize PT_OPENBSD_RANDOMIZE in linker scripts.
