# The version which ends up here is something like

# -$(abiname), so that the variables get the values:
# suffix=$(flavour)
# prefix=$(version)-$(abiname)
# prefix is then used to form a destination directory
# to link to. For cases with subarch we need to link
# to kernel-headers-$(version)-$(abiname)-$(subarch),
# not just kernel-headers-$(version)-$(abiname). Note
# that the append_subarch substitution must contain a
# dash, if it is non-empty.

# Here we need to find the kernel architecture which

# make-kpkg export it to this script.

# Currently we'll have to do some fiddling here For
# example for sparc we need to map sparc32* to 'sparc'
# and sparc64* to 'sparc64'. The default for other
# arches is the name of the architecture.
