[PATCH v2 02/14] perf: Use -iquote for local include paths

[Josh Poimboeuf <jpoimboe@redhat.com>]

If there's a local header file which has the same name as a system
header file, '#include <header.h>' will mistakenly include the local
file instead of the system file.

With the next patch we'll have a string.h file.  Use the '-iquote'
option to prepare for it so that '#include "string.h"' picks up the
local version.

Note that after applying this patch, a 'make clean' is needed to clear
out the old versions of tools/perf/tests/llvm-src-*.c.
