This is bogus since the first 4 entries are LE while the last one can be BE.

armv5tele and armv5tebe don't exist in OE.

I think conf/machine/ixp4xx.conf shouldn't be used, but conf/machine/ixp4xxbe.conf or
ixp4xxle.conf should be used instead. Each of those machines should set PACKAGE_EXTRA_ARCH
independantly.
