[aarch64-port-dev ] [PATCH] [jdk8u] Remove unused template which breaks builds with GCC 6

[Andrew Hughes]

Webrev: http://cr.openjdk.java.net/~andrew/aarch64-8/gcc6/webrev.01/

The min template:

template <class T> static const T& min (const T& a, const T& b)

causes the build to fail with GCC 6 [0], where the default C++ standard
(-std=gnu++98) has to be explicitly specified, as the default has changed.

/builddir/build/BUILD/java-1.8.0-openjdk-1.8.0.72-5.b15.fc24.aarch64/openjdk/hotspot/src/share/vm/utilities/globalDefinitions.hpp:1113:18: warning: variable templates only available with -std=c++14 or -std=gnu++14

 }
 ^

The template appears to be unused and removing it allows the build
to succeed with GCC 6.

Ok to push?
