> Just drop -mbuild-constants.

Thanks for the hint Uroš, but I'm not sure if one can do that, this option is
from [1]. I do not have the background on this, but it reads as there was a
reason "Use -mbuild-constants to prevent the compiler using static data" to set
this which seems more breaking than my current workaround (reduce -O2 to -O1).
