That's the point: qemu is not supposed to link against my host 
libraries. It should use OpenEmbedded staging libraries for this. Also, 
the recipe explicitly points the qemu build to the native staging 
"includes" directory already. After adding gnutls and ncurses to the 
dependencies qemu linked the native staging libs as expected, and the 
build is now successful.

Anyway, qemu _does_ link against gnutls and ncurses at some point in its 
build process. So why not provide these dependencies? I guess it could 
be important for a target build, too.

Regards,
Thilo
