Qt 4 has module QtMultimedia

I don't know how common dependencies of Qt and other (static)
libraries act in this situation.

This work is already done. See the last lines of file src/qtbase.mk:

$(PKG)_BUILD_SHARED = $(subst -static ,-shared ,\
                      $($(PKG)_BUILD))

To make use of this definition, you'd better to compile all  MXE
libraries shared:

$ make MXE_TARGETS=i686-w64-mingw32.shared

Nevertheless consider moving to stable branch of MXE. It is less buggy
and has both Qt 4 and Qt 5 as well as master branch.
