If you have GCC installed iwth your host, g++ should be there as well.
Since you are using ubnut did you do: sudo apt-get install build- 
essential bison texinfo gawk && sudo dpkg-reconfigure dash ?

eglibc doesn't require those to build. It may request them, but it  
certainly does not require them to build.

There is probably something specific to the headers. Never have built  
alpha, so am not sure.

You could browse the clfs-dev archive from before 2007 or so and see  
if there is any info on the alpha book when it was being developed.
