freebsd/sys/conf/Makefile.alpha
Peter Wemm f31f62f872 Further sync Alpha and i386 Makefiles. Remove KERNFORMAT = elf stuff as
it's always true on these platforms (and is likely to be on others as
well since loader is the one that is configured for whatever the boot
requirements are)

# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/alpha/conf/``machineid''
# after which you should do
# config machineid
# Generic makefile changes should be made in
# /sys/alpha/conf/Makefile.alpha
# after which config should be rerun for all machines.

# Which version of config(8) is required.
