Use ccache to cache all compiles between builds. Many python extensions are built from source each time an image is built. Repeating these is wasteful, so ccache is employed to eliminate that waste. A cache dir outside the chroot is used to speed up subsequent image builds.

Place /usr/lib64/ccache in PATH ccache wasn't being used on fedora as the symlinks are in lib64. Change-Id: I810558799dd2382b36b5112e435b74fd5caa8ccf 2014-04-23 00:11:40 +00:00			`for CCACHEDIR in "/usr/lib/ccache" "/usr/lib64/ccache" ; do`
