(cherry picked from commit 3aaaa2efde)
This register set contains the values of the fsbase and gsbase
registers. Note that these registers can already be controlled
individually via ptrace(2) via MD operations, so the main reason for
adding this is to include these register values in core dumps. In
particular, this will enable looking up the value of TLS variables
from core dumps in gdb.
The value of NT_X86_SEGBASES was chosen to match the value of
NT_386_TLS on Linux. The notes serve similar purposes, but FreeBSD
will never dump a note equivalent to NT_386_TLS (which dumps a single
segment descriptor rather than a pair of addresses) and picking a
currently-unused value in the NT_X86_* range could result in a future
conflict.

This register set exposes the per-thread TLS register. It matches the

Add a elf_putregnote() helper to build the ELF note for a register
set. Once nice result of this approach is that this reuses the
kernel's support for generating 32-bit register sets for 32-bit
processes avoiding the need to duplicate that logic in elf32core.c.

It's a drop-in replacement for https://github.com/Gandi/ctld_exporter,

The current implementation of sysctlbyname() does not support the user
sub-tree. This function exits with a return value of 0, but sets the
passed string buffer to an empty string.
As a result, the whereis program did not use the value of the sysctl
variable "user.cs_path", but only the value of the environment
variable "PATH".
This update makes whereis use the sysctl function with a fixed OID,
which already supports the user sub-tree.

Use strtoll() to parse the argument of the -S option.
FreeBSD has supported 64 bit file offsets for more than 25 years on
all architectures and off_t is a 64 bit integer type for that reason.
While strtol() returns a 64 bit value on 64 LP64 architectures, it
is limit to 32 bit on e.g. i386. The strtoll() function returns a 64
but result on all supported architectures and therefore supports the
possible file lengths and file offsets on 32 bit archtectures.

The man page states that "-t %+" prints time information in the same

elfdump -E on an empty file would complain "Invalid argument" because
it tried to mmap zero bytes. With the -E flag, elfdump should
simply exit non-zero. For tiny files, the code would reference off
