7179349 misses updating new build makefiles

[Mike Duigou]

A fix was recently integrated into JDK 8 mainline repo which breaks new-infra builds on MacOS X.

http://hg.openjdk.java.net/jdk8/awt/jdk/rev/d6cba7bfbb3d

The logic for creating the icon file created is not present in the new build infra makefiles. (jdk/makefiles)

The ToBin.java program can also be omitted with something like the following:

(/bin/echo "static unsigned char sAWTIconData[] = {"; hexdump -v -e '"\t" 32/1 "%u, " "\n"' $(ICON) ; /bin/echo "};") > $(ICON_DATA)
