The --enable-dependency-tracking option was added to workaround build issues in libatomic. This fixes that build problem properly and removes the flag since the dependency tracking code appears to be full of races which are much deeper and harder to fix. As per the automake manual, dependency tracking is only useful and worth the build performance cost if you are doing more than one compile of the same source code which in most cases we are not so this is a good thing anyway.

gcc 4.8 won't build with --disable-dependency-tracking since the *.Ppo files
|
|
don't get created unless --enable-dependency-tracking is true.
|
|
|
|
This patch ensures we only use those compiler options when its enabled.
