[Crash-utility] [PATCH 0/5] let make flexible for multiple host

[Toshikazu Nakayama]

Hi Dave,

This patch set will make configure or build flexible for host environment,
in particular dealing with cross compiler.
Please consider about this proposal.

patch#1:
 By declaring tables about target and host relationships,
 cleanup corresponding code and the new build combination will be
 adapted briefly.

Remaining patches:
 Try to relieve cross compiler burden by using explicit host_cross option.
 I'm using cross compiler environ host=x86 for target=ppc,
 and might attempt target=<another arch> in the near future.
 I stocked private patches to accomplish cross compiling
 but I'd like to discard them permanently with your agreement.

Thanks,
Toshi

  Makefile: wrap cc, gcc and ar with common make valiables
  make: add host_cross option
  build_data: handle CC valiable
  configure: handle cross compile with target=ppc host_cross=x86
