phonon fails to build from source with the following error (the build
log is from s390x, but reproducible on other architectures):

The problem is that pow is used without including <cmath>, that said
upstream has choosen a different solution and use the Qt function
instead, as shown in the patch below.
This package will block the s390x bootstrapping soon, so it would be
nice if the fix can be uploaded shortly. Thanks in advance.

pulse: Use qPow() as pow() is sometimes not found.
