Yes, as long as you have ALL the necessary tools and packages to compile
all components, the source-tar-ball contains all the necessary code to
build xen itself, tools, ioemu bits and whatever else you may need. 

There is a hitch in building the "firmware" which is part of tools to
run hvm - you need a 16-bit compiler which you have to go somewhere to
download, it's not normally distributed with the distributions... If you
do "cd <xen-root>/tools/firmware" and type "make", it'll suggest a
location to download from - you probably also need to build this, and
when I last tried, it didn't build correctly in 64-bit mode, so try
building with "linux32" or some such set...
