The last two are not required (afaik). Setting CROSSCOMPILEDIR does include
cross.def and sets CrossCompiling too.

I'm doing crosscompile for cygwin on linux and I've no problems. But I've adjusted
some files in config/imake and config/makedepend to workaround some problems.

I've noticed this too. Just write all make output to a file and grep for "***"

make World CROSSCOMPILEDIR=... 2>&1 | tee makelog

and in another xterm I wathc the logfile and search for "***" (regex \*\*\*) and
try to fix the errors.

You don't have fontconfig (cross version) installed. Add this to your host.def:

#define HasFontconfig NO
#define HasExpat NO
#define HasMotif NO
#define HasMotif2 NO

maybe there are some other libraries which are not present as crosscompile versions
which have to be added to. make World will then compile a local fontconfig and expat 
library and discard everything that requires motif.

You could add
#define BuildClients NO
#define BuildFonts NO
#define BuildDocs NO
#define BuildServers YES

to host.def
