Even if using ICU for transcoding, there's still some stuff in Xerces
(MacOSPlatformUtils.cpp) which in the end pulls in things from CF - e.g.
file related calls.

Attached is a hackish patch for Xerces 2.8.0 which makes it use the
FreeBSDPlatformUtils.cpp stuff when compiling for OS X. It should be
considered a proof of concept, but at least it allows to compile a
version of libxerces-c.28.0.dylib without any dependency on
CoreServices/CoreFoundation. Of course, the usual "use at your own risk"
disclaimer applies to anybody compiling Xerces with this patch
(runConfigure needs to be called with "-p macosx -n socket -t icu").
