I tried it out and ran into a bit of a snag:

$ bash ../autoconf/configure
checking for readlink... /usr/bin/readlink
checking for apt-get... no
checking for yum... yum
checking for grep that handles long lines and -e... /usr/bin/grep
checking for gawk... gawk

[ snip ]

checking if dynamic link of stdc++ is possible... yes
checking if static link of stdc++ is possible... no
configure: Static linking of libstdc++ was not possible reverting to
dynamic linking.
checking how to link with libstdc++... dynamic

====================================================
A new configuration has been successfully created in
/home/omajid/devel/jdk8-build/build/linux-x64-normal-server-release
using default settings.

Configuration summary:
* Debug level:    release
* JDK variant:    normal
* JVM variants:   server
* OpenJDK target: OS: linux, CPU architecture: x86, address length: 64
* Boot JDK:       /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.3.x86_64

Build performance summary:
* Cores to use:   4
* Memory limit:   3753 MB
* ccache status:  not installed (consider installing)

Build performance tip: ccache gives a tremendous speedup for C++
recompilations.
You do not have ccache installed. Try installing it.
You might be able to fix this by running 'sudo yum install ccache'.
$ make images

As you can tell, I don not have static c++ linking available, but
linking dynamically is failing too. I have built other variants of
openjdk 7 and 8 on this machine before using dynamic linking
(STATIC_CXX=false), so I was expecting this to work. Is there any
additional information I can provide to help?

Thanks,
Omair
