Subject: [PATCH 07/16] perf test: Add Build file to dependencies for llvm-src-*.c

From: Josh Poimboeuf <jpoimboe@...hat.com>

Because the Build file writes source code to the generated llvm-src-*.c
files, it should be listed as one of the dependencies, so that any
future changes to the code being echoed won't require a 'make clean'.
