MDEXTRA_SUFFIXES.${KERNEL} -> MDSET.${FILENAME}.suffixes
${KERNEL.${_K}}.post -> MDSET.${FILENAME}.post
This allows "default" rules for for MDSETTARGETS with FILENAMEs of "-"
by defined MDSET.-.post & MDSET.-.suffixes
- Document the above
- Use the above appropriately in various Makefiles
- Be a be quieter when building these kernels
- Add .WAIT syncs so that multiple kernels aren't built in parallel, because
the temporary filename is the same, and it also avoid hairy magic in
syncing the targets generated from MDSET.${FILENAME}.suffixes with
the master target for that ${FILENAME}

# KERNEL IMAGE FILENAME
|
|
# The kernel ${KERNOBJDIR}/${KERNEL}/netbsd is

# ${MDSETIMAGE} with ${IMAGE}, ${STRIP}ped,

# Optional variables:

# MDSETDIR Where to install release kernels.
|
|
# MDSET.${FILENAME}.post For each kernel named ${FILENAME},
|
|
# execute this after ${NM} / ${STRIP}.
|
|
# Kernel is available as netbsd.tmp.
