bitbake.conf/tune files: Adjust PACKAGE_EXTEA_ARCHS
RFC PATCH 1/1 bitbake.conf/tune files: Adjust PACKAGE_EXTEA_ARCHS
There is a problem with the current PACKAGE_EXTRA_ARCHS implementation since its impossible to control which extra architectures sort higher than TARGET_ARCH and which sort lower. In the x86 case for example, TARGET_ARCH might be "i586", i486 should be lower than this and i686 should be higher. There are also complications where its easy to inject duplicate entries into the variable.
I tried various versions of this patch and concluded that it was simplest just to force the tune files to include TARGET_ARCH in the list in the right place if they're planning to customise it themselves. Other approaches with appends and prepends just complicated the code for no good reason.
The TARGET_ARCH definitions should also move to the tune files but I'll leave this for a separate patch.

Since there were no objections to this (and I chatted to some people over jabber about it too), I'm going to merge this.
Cheers,
