Build error on jdk8/tl project - Thread.o:(.data.rel+0xbc): undefined reference to JVM_SetNativeThreadName

[Martijn Verburg]

Hi Alan/Max,

You're both right, I've actually been working from
http://hg.openjdk.java.net/jdk8/tl/jdk as opposed to
http://hg.openjdk.java.net/jdk8/tl - thanks for catching that with the
limited info I posted.

Will start from scratch from http://hg.openjdk.java.net/jdk8/tl and see
where the yellow brick road takes me :-)

Cheers,
Martijn
