Yeah target is fine. And yes they are needed on the host to build 
libraries for the target.

Don't really understand how this will solve the problem ? The *.in 
versions of the scripts look like this. So they are created at 
"automake-time"

less mcs.in
#!/bin/sh
exec @bindir@/mono $MONO_OPTIONS @mono_instdir@/2.0/mcs.exe 
-lib:@mono_instdir@/2.0 -lib:@mono_instdir@/3.5 "$@"

My idea was to add a $MONO_PREFIX environment variable to the scripts 
and set that in the target build .make file. On the target itself the 
MONO_PREFIX variable would be not set and the path would be /usr/bin as 
expected.
