%description
These are the GNU binutils.  These are utilities of use when dealing
with binary files, either object files or executables.  These tools
consist of the linker (ld), the assembler (gas), and the profiler
(gprof) each of which have their own sub-directory named after them.
There is also a collection of other binary tools, including the
disassembler (objdump) in this directory.  These tools make use of a
pair of libraries (bfd and opcodes) and a common set of header files
(include).

Summary:       ELF linker
Requires:      %{name} = %{version}

%description gold
gold is an ELF linker.  It is intended to have complete support for
ELF and to run as fast as possible on modern systems.  For normal use
it is a drop-in replacement for the older GNU linker.
