That doesn't work for me  fails with:

checking build system type... config.sub: missing argument
Try `config.sub --help' for more information.
configure: error: /bin/sh ./common/autoconf/build-aux/config.sub   failed


I will try a completely new clone and build...

Yes - we did do the basics  (including teaching toolschain about xlc )

The codebase has moved on a little since then so we have a couple more changes to come for src/solaris/native/common/jdk_util_md.h and src/solaris/native/java/io/io_util_md.c b/src/solaris/native/java/io/io_util_md.c 

Let me make sure I can reproduce your situation and then lets talk about the next changes required..
