Reopen, because the bug isn't fixed.

This patch deleted empty.cpp, instead of reverting to previous state (empty file), so now the gccdepends config test always fails.

Ooops, I added empty empty.cpp back in r136226.

Simon, Tor Arne: Is the original bug still valid? 
Or can we close this as WONTFIX?

[Tor Arne Vestbø]

Barring the broken rollout, the original bug is now reintroduced. We should perhaps figure out how it broke the build so we can fix the original patch.

The question is very good after 2 months .... Who remembers what happened that time. Let me try to find the bot history.

[Csaba Osztrogonác]

I checked 2-3 bots history ... but I can't find any useful information. :-/
I can't remember which bots / EWS were broken that time. Let's try to debug
it on monday.

It means that the "GNUmake gcc_MD_depends" case was always broken
with all-in-one files. But the accidentally missing empty.cpp simple 
disabled "GNUmake gcc_MD_depends" everywhere. That's why nobody noticed it.
