it’s easy to check: Just run
$ ghc --show-iface /usr/lib/ghc/base-4.7.0.2/System/Info.hi|grep Dep
addDependentFile "/build/ghc-LIQtDg/ghc-7.8.4/includes/ghcplatform.h"
addDependentFile "libraries/base/dist-install/build/autogen/cabal_macros.h"
addDependentFile "/usr/include/stdc-predef.h"

If you see the build path appearing there, you are affected by the bug.


Greetings,
Joachim
