[PATCH] scan-build: Add --triple option to scan-build

[Honggyu Kim]

Hi all,

I wrote this patch because I had some problem generating a clang static analysis report for ARM Linux kernel code. Since it uses
some target specific flags for ARM, I got the following error message during analysis.

error: unknown target CPU 'armv7-a'

I have checked scan-build script, but there was no way to pass target triple information to clang, so clang thinks that the source
code can be compiled for host machine, x86_64. This patch adds --triple option to fix this problem.

With this patch, I was able to generate clang static analysis report for ARM Linux kernel code with the following command:
$ scan-build --use-cc=arm-linux-gcc --triple=arm-linux-gnueabi make ARCH=arm CROSS_COMPILE=arm-linux-

Please let me know your opinion.
I appreciate all your comment.

Thanks,
Honggyu
