distro/minimal.conf: Dont keep CACHE as weak assignment.

* As this is a weak assignment and bitbake.conf has a proper
  assignment and bitbake.conf is included before distro conf
  file it leaves this weak assignment as no-op. The problem happens
  when using minimal but changing libc from eglibc to uclibc then
  it will use same cache directory and then its infact wrong.
