add libelf from elftoolchain r3669

A 2 clause BSD licensed implementation of the SVR4 ELF API also
implemented by mr511.de libelf (devel/libelf in ports) and elfutils.

It is being added to base to allow Mesa to use it in future.

shlib major is higher than devel/libelf and pkg-config version is 0.8.2
to pass a glib2 configure test so this can replace the use of
devel/libelf in ports.

.Sh NAME
.Nm elf_end
.Nd release an ELF descriptor
.Sh LIBRARY
.Lb libelf
.Sh SYNOPSIS
.In libelf.h
.Ft int
.Fn elf_end "Elf *elf"
.Sh DESCRIPTION
Function
.Fn elf_end
is used to release the resources associated with an ELF descriptor
pointed to by argument
.Ar elf .
This descriptor must have been allocated by a previous call to
.Xr elf_begin 3
or
.Xr elf_memory 3 .
For programming convenience, a NULL value is permitted for argument
.Ar elf .
.Pp
A call to
.Fn elf_end
decrements the activation count for descriptor
.Ar elf
by one.
The resources associated with the descriptor are only released
with its activation count goes to zero.
.Pp
Once function
.Fn elf_end
returns zero, the ELF descriptor
.Ar elf
will no longer be valid and should not be used further.
.Sh RETURN VALUES
Function
.Fn elf_end
returns the current value of the ELF descriptor
.Ar elf Ap s
activation count, or zero if argument
.Ar elf
was NULL.
