Rob,
after rm -fr the jamVm directory, extracting it again and running the
configure below, finally compilation succeeded!
I guess make clean was not cleaning my configure mess.
For anybody that has the same problem while crosscompiling, i solved it by
using both the --host and --build flag (thanks Robert!)
