freebsd/sys/conf/Makefile.alpha
Marcel Moolenaar 7621bfff0f Allow the source root `S' to be overridden by defining it only when
it isn't already defined. It enables config(8) to create the kernel
build directory where it wants.

# This makefile is constructed from a machine description:

# Most changes should be made in the machine description
# /sys/alpha/conf/``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.
