Well those instructions should work, although obviously you can stop 
once you have built and installed your new set of binutils.

Is that a problem ?  The config.sub script automatically expands 
"arm-elf" into "arm-unknown-elf".  This is OK.  The middle part of the 
triplet is the manufacturer's name and "unknown" is a perfectly common 
value.  The binutils should still build correctly.

OK, but please be careful to construct the linker command line 
correctly.  (I mentioned using gcc to drive the linker because quiet a 
few bug reports that we receive are due to people trying to run the 
linker directly and not appreciating the work that gcc does in 
constructing the command line).
