Hi David,

I thought about that too. But I was unable to find info on OpenJDK +
SPARC + Linux. Is that combination even supported? The README doesn't
list it:
http://hg.openjdk.java.net/jdk6/jdk6/raw-file/tip/README-builds.html#MBE

The option seemed more like a relic from Solaris + SPARC config rather
than a requirement for Linux + SPARC.

Cheers,
Deepak
