1. RDEPENDS_${PN} = "qemuwrapper-cross" wont work since TARGET_ARCH 
detected in qemuwrapper-cross recipe will be SDKMACHINE when
compiled as nativesdk-qemuwrapper-cross. (I know, nativesdk-*-cross 
should not be done).
I have not found a way to retrieve the real target architecture during 
a nativesdk build.

Also, we can't add qemuwrapper to the nativesdk sysroot, since we may 
have mutiple target sysroots which have different
qemuwrapper settings.
