David Carrillo-Cisneros 3866058ef1 perf tools: Robustify detection of clang binary 
Prior to this patch, make scripts tested for CLANG with ifeq ($(CC),
clang), failing to detect CLANG binaries with different names. Fix it by
testing for the existence of __clang__ macro in the list of compiler
defined macros.
