(urgent) RFR: JDK-8074072: Race condition in build since JDK-8072842 can cause failed builds on Solaris

[Erik Joelsson]

Hello,

A race condition, possibly leading to a failed build on Solaris, was 
introduced with JDK-8072842. Here is a fix adding the necessary 
dependencies to solve this for now, until the proper solution in 
JDK-8064808 can be fixed.

The fix in Tools.gmk has long been needed, but happened to work because 
the first user of these tools used to be java.base-libs and no other 
native code could be compiled before it.
