As an example, the last part of the configure output might look like this:

Tools summary:
* Boot JDK:       java version "1.8.0" Java(TM) SE Runtime Environment 
(build 1.8.0-b132) Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, 
mixed mode)  (at /localhome/java/jdk-8-fcs-bin-b132-linux-x64)
* Toolchain:      gcc (GNU Compiler Collection)
* C Compiler:     Version 4.8.2 (at /usr/bin/gcc)
* C++ Compiler:   Version 4.8.2 (at /usr/bin/g++)

Build performance summary:
* Cores to use:   14
* Memory limit:   28134 MB

WARNING: The result of this configuration has overridden an older
configuration. You *should* run 'make clean' to make sure you get a
proper build. Failure to do so might result in strange build problems.

The following warnings were produced. Repeated here for convenience:
WARNING: Option --with-custom-make-dir is deprecated and will be ignored.
