  Yes, I would be very much in favour of that. It also solves the issue 
that some configure systems don't deal very well with a CC that contains 
spaces. And for external toolchains, it's nice that the actual options 
that are passed to the external toolchain are also visible to ccache.

  I see two issues however:

- How to deal with HOSTCC?

- How to deal with HOSTCC_NOCCACHE? (TARGET_CC_NOCCACHE can probably be 
removed)


  Anyway, for cmake the solution proposed by Samuel works even better.

  Regards,
  Arnout
