[OE-core] [PATCH RFC] bitbake.conf/tune files: Adjust PACKAGE_EXTEA_ARCHS

Richard Purdie richard.purdie at linuxfoundation.org
Tue Mar 15 20:31:26 UTC 2011 

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.
