It doesn't seem to work, or I'm doing something wrong :). For example,  
the following line, when inserted into static analyzer, prints  
"TARGET_NAME env variable is set: 0":
fprintf(stderr, "TARGET_NAME env variable is set: %d\n",  
getenv("TARGET_NAME") != NULL);

Although xcodebuild does set the TARGET_NAME when compiling (I dump  
all env variables from xcodebuild with a Run Script Phase). The only  
env variables related to compiling I see from the clang process are  
CCC_ANALYZER_ANALYSIS, LDPLUSPLUS, CCC_ANALYZER_HTML, CLANG and CC.
