In resolving conflicts that happen because I haven't merged some other
files (thread_stack, etC) I noticed that this patch introduces something
that is explicitely listed in a .gitignore file:

[acme@zoo linux]$ git show d316f16dddd8c7780c727bbd507338e4147c9280
commit d316f16dddd8c7780c727bbd507338e4147c9280

    perf tools: Add feature checks to .gitignore


+++ b/tools/perf/.gitignore
@@ -24,3 +24,4 @@ config.mak.autogen
[acme@zoo linux]$

So I think we should use some different name for this test-compile.c

I'll leave those two csets out of this pull req, so that you can rebase
what is left on top of what is being merged and we can do one more
progress step in having all this merged, ok?
