Building complete images is slower than a default build ("exploded 
image") and most often not needed.

Try doing it in separate steps:
make hotspot
make jdk
make images

and check how long each step takes.

Is it because the gcc version I have to use on Yosemite is older (gcc 4.2 supplied with Xcode 4.6.3)? If yes, any ideas on speeding up the incremental builds?
