John Ericson 7018dfb9f4 binutils and cctools: Prefix derivation names with target for cross
We want platform triple prefixes and suffixes on derivation names to
be used consistently. The ideom this commit strives for is

 - suffix means build != host, i.e. cross *built* packages. This is
   already done.

 - prefix means build != target, i.e. cross tools. This matches the
   tradition of such binaries themselves being prefixed to disambiguate.]
   Binutils and cctools, as build tools, now use the latter

# - as: as above
# - ar: the binutils one prodices .a files that the cctools ld doesn't like
# - ranlib: for compatibility with ar
# - dsymutil: soon going away once it goes into LLVM (this one is fake anyway)
# - otool: we use it for some of our name mangling
# - install_name_tool: we use it to rewrite stuff in our bootstrap tools
# - strip: the binutils one seems to break mach-o files
# - lipo: gcc build assumes it exists
# - nm: the gnu one doesn't understand many new load commands
