Hi,

I am sorry for the late response, I'll try to find the information for
cross compiling, should have it somewhere..

Those instructions should also explain a bit about cross compiling APR. For
that work buildroot [1] was used, perhaps it might be a good starting point
to look if they support APR as one of the default modules.
