Yes it does build!
I have done sucessfull full bootstrap builds of icedtea 7 + shark on 
ia32 and amd64 using Ubuntu 10.04.
For these two builds I have built Shark in combination with the Ubuntu 
supplied LLVM 2.7 package.

This are how i configured my build on amd64:

$ hg clone http://icedtea.classpath.org/hg/icedtea
$ mkdir icedtea-shark
$ cd icedtea
icedtea$ ./autogen.sh
icedtea$ cd ../icedtea-shark
icedtea-shark$ ../icedtea/configure --enable-shark --with-parallel-jobs=4
icedtea-shark$ time make

... and 96min later after processing docs etc...

IcedTea is served: /media/_/icedtea-shark/openjdk.build
...

icedtea-shark$ ./openjdk.build/j2sdk-image/bin/java -version
java version "1.7.0_89-icedtea"
OpenJDK Runtime Environment (IcedTea7 1.14-pre+r90b892525f1b) (Ubuntu 
build 1.7.0_89-icedtea-b89)
OpenJDK 64-Bit Shark VM (build 18.0-b02, mixed mode)

Thanks,Ii will keep this in mind and backport any fixes needed from the 
"main" Shark hg if the get a new Hotspot.
Will we get a new Hotspot hs19 after the bump?

For what i know, the following distributions package Shark:

Debian, Ubuntu
http://packages.debian.org/search?keywords=openjdk-6-jre-zero
for amd64 armel i386 and powerpc

Ångstrom.
http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-shark-vm-shark

I have also started to see some Shark success reports where users starts 
to recommend the use of Shark on small embedded servers.
