Consistently use ${RELEASEDIR}/${RELEASEMACHINE} instead of
${RELEASEDIR}/${MACHINE} (Paul Ripke)

Fix comment. We do not use the a.out format anymore...

Clear STRIPFLAG after include bsd.own.mk; it can be modified by mk.conf via
bsd.own.mk.

branches: 1.16.6; 1.16.10;
Use <bsd.klinks.mk>

Build boot loaders without unwind tables.

Don't depend on cat pages to be installed, just run mandoc here.
Also provide a HTML version for user of modern technology.

branches: 1.13.4; 1.13.8;
Convert to using -nostdinc, and set include paths and create symlinks
so that we include the source tree's sys/, machine/ and m68k/ headers,
and only as a last resort use DESTDIR's /usr/include. For some reason
the host's bootinfo.h got included ahead of the x68k variant, causing
a build failure in my case.

branches: 1.12.84; 1.12.90;
Support MAKEVERBOSE

branches: 1.11.18; 1.11.32; 1.11.36; 1.11.44;
Install release files under "${RELEASEDIR}/${MACHINE}/..." instead of
"${RELEASEDIR}/...".

${RELEASEDIR} is never cleaned , and ${RELEASEDIR}/${MACHINE} is only
cleaned if UPDATE is not defined.

Place catman in RELEASEDIR/installation/misc.

Make ELF kernel loadable, by itohy-san.

MKfoo=no -> NOfoo

New target: release.

${MAKE} print-objdir -> ${PRINTOBJDIR}

Another steps for ELF.
- register prefix
- machine/asm.h
- deprecated -T option for ld(1)

branches: 1.4.20;
Merged minoura_x68k_bus_h branch.

convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

branches: 1.2.4;
Moved the manual to share.
Added -L for libc.
Use `&&' instead of `;' for cd and print-objdir in order to avoid
infinite fork() if chdir failed.

New boot program.
Load and execute NetBSD/x68k kernel from Human68k.
