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

[Weijun Wang]

A partial build is you go inside tl/jdk/make/ and run make there, it 
only builds the tl/jdk part, and the output goes to 
tl/jdk/build/linux-i586. A full build is you go inside tl/ and run make 
there, it builds all repos, and output goes to tl/build/linux-i586.

I suspect you're doing a partial build because these 2 options appear in 
the error:

     -I../../../build/linux-i586/tmp/java/java.lang/java/CClassHeaders
     -I../../../src/solaris/javavm/export

This means "src" and "build" are at the same directory levels. Therefore 
the "build" is inside tl/jdk.
