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.

+and
+.Fn elf64_fsize
+return sizes for files of class
+.Dv ELFCLASS32
+and
+.Dv ELFCLASS64
+respectively.
+Function
+.Fn gelf_fsize
+returns the size for the class of ELF descriptor
+.Ar elf .
+.Sh RETURN VALUES
+These functions return a non-zero value in case of success, or zero in
+case of an error.
+.Sh ERRORS
+These functions may fail with:
+.Bl -tag -width "[ELF_E_RESOURCE]"
