Subject: [PATCH] simpleitk: enable SimpleElastix module

Note that building SimpleITK with shared libraries had to be disabled
when building against Elastix (which doesn't support building with
shared libraries for some reason) due to a linker error.
However, the Python package correctly builds the needed shared objects.
