ARCH is already set in ../config.mak.
"case" would be a better shell construct than "ifeq" for this
translation.

Rather than adding an ifdef for every architecture here, can we define a
HEADERS variable and do something like
for hdr in $HEADERS ; do
$(call hack, $hdr)
done
HEADERS could be defined in the case statements you're going to add. ;)

Why are these headers not common?
