%description
Binutils is a collection of binary utilities, including ar (for
creating, modifying and extracting from archives), as (a family of GNU
assemblers), gprof (for displaying call graph profile data), ld (the
GNU linker), nm (for listing symbols from object files), objcopy (for
copying and translating object files), objdump (for displaying
information from object files), ranlib (for generating an index for
the contents of an archive), readelf (for displaying detailed
information about binary files), size (for listing the section sizes
of an object or archive file), strings (for listing printable strings
from files), strip (for discarding symbols), and addr2line (for
converting addresses to file and line).

This is a build of a specific older version of binutils, required
to create a reproducible build of the fundamental SGX enclaves
that matches the pre-built signed binaries provided by Intel.
