Architecture: earm
Machine: zaurus
>Description:
After oarm to earm migration, it looks build.sh defines
MACHINE_ARCH=earm by default for zaurus.
However all Zaurus models PXA210/250/255/270 XScale (i.e. V5TE core)
so particular reason to use earm.

I wonder if we should change it from earm to earmv5.
(a bit annoying to use pkgsrc binaries built for other arm ports)

>How-To-Repeat:
Code inspection.
