[scan-build] Patch to scan-build tool to support "--target=<value>" flag

[haowei]

Summary

The scan-build script provided by clang can be used to detect defects in code in the compile time. However, we discovered that the "--target=<value>" flag in clang is not properly handled by this script, which results in failures when analyzing projects that have used this flag in their makefile.

This single line of change allows scan-build script to properly handle the "--target=<value>" flag

I don't have commit access, so could you commit this patch?
