I've committed a workaround for this in the form of:

http://git.pokylinux.org/cgit.cgi/poky/commit/?h=master&id=9975c00c1a6a9ae1c39678dec0986f4c62418c96

which means perl-native will always be rebuilt but at least builds
should then work.

I've left bug #602 open as a hint to investigate a proper fix for this,
maybe by setting an environment variable and/or a wrapper script.

At present the aim is to get the sstate packages working, then we can
look at details like this.

Cheers,

Richard
