[8u] Request for Approval and Review: JDK-8136980: build for 8u65 and 8u66 for solaris platforms is failing

[Erik Joelsson]

Hello,

Please approve and review this fix for 8u.

My last fix for this issue, JDK-8136691, was not enough. I made a 
mistake while verifying the fix and the problem is still there.

There are more discrepancies between Solaris and the other platform 
makefiles. The excludeSrc.gmk file is not included anywhere when 
building on Solaris. The variable Src_Files_EXCLUDE is overwritten in 
vm.make instead of appended to, so even when including excludeSrc.gmk, 
it wasn't enough. The other platform specific buildtree.make files also 
set INCLUDE_TRACE in the generated makefile.
