# - ld: binutils doesn't provide it on darwin
# - 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
