RFR: JDK-8168636 More detailed information about native libraries in build log

Tue Oct 25 07:42:51 UTC 2016

When building native libraries or executables, currently only the 
basename of the library is printed, e.g. libjvm.so. This is not always a 
unique identifier, and even when it is, it's not always helpful in 
understanding what is being built.

Example of output without this patch:
Creating libjvm.so from 32 file(s)

Example of output with this patch:
Creating hotspot/variant-server/libjvm/gtest/libjvm.so from 32 file(s)
