[scan-build-py] Patch to fix "-analyzer-config" option
I noticed that when I use "-analyze-config" option in scan-build-py, it
behaves differently from original perl based scan-build.
For example, command:
$ scan-build -analyzer-config ipa=basic-inlining make
Will work without any issues on perl version of scan-build. But on
scan-build-py it will throw an error message "error reading
'ipa=basic-inlining'".
After debugging, it turns out that the scan-build-py does not put
"-analyzer-config" flag in front of the analyzer config flags (in this
case is the "ipa=basic-inlining") in the final clang command line. This
patch fixes this issue.
