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

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 Toshikazu Nakayama (5): configure: retake the way of host compiler detection 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 Makefile | 144 +++++++++-------- configure.c | 441 ++++++++++++++++++++++----------------------------- extensions/Makefile | 10 +- extensions/sial.mk | 6 +- extensions/snap.mk | 6 +- 5 files changed, 289 insertions(+), 318 deletions(-)
