Bug: https://bugs.openjdk.java.net/browse/JDK-8220093 /Erik
In addition to this, the devkit generator makefiles are getting some
touchups. The ccache build output is moved to the correct location.
Fixed an issue with creating tar files. Changed binutils to use gold by
default. Also fixed the linker version check in configure to be
compatible with gold.
