[PATCH] nativesdk-rpm: Add wrappers for nativesdk support

[Ovidiu Panait]

When installing the SDK to a non-default path, running "rpm --showrc" from the
sdk will produce the following error:
error: Unable to open /opt/poky/2.4+snapshot/sysroots/x86_64-pokysdk-linux/usr/lib/rpm/rpmrc for reading: No such file or directory. 

Fix this by adding wrappers that dynamically export the RPM_CONFIGDIR,
RPM_ETCCONFIGDIR and MAGIC environment variables, pointing to the proper
sdk locations.

Can this be done without copy-pasting an existing function please?

The code can't run in class-target, this would screw up the target.
The code in class-native has a different set of arguments to the create_wrapper.
The rm -rf ${D}/var is not done on class-native, but is done on class-target.

So no.  We need two copies, as they are different.
