69edc948f4 Some man pages need tbl to make their man page. This adds support for 
tbl in building man pages.  If the variable USETBL is defined, the
rules for making the man pages include tbl before nroff.

This supports at least 3 man pages in the tree.

5fd7ce7066 These updates to the build allow building against include files 
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

346af6eeff More table-driven changes: split CPICFLAGS into separate flags, to 
support the two different incompatible rules for build .so files from
.S source on both NetBSD and binutils toolchains:

	 ${CPP} | ${AS} for syscalls
	 ${CC}   	for non-syscalls
for which the different toolchains's ${AS}  requires diffferent flags.

1d20ab5d2e if 'clean' is not already defined, rather than simply defining it with 
a bunch of rules, define a clean{kmod,lib,prog} target with the rules,
and have both clean and cleandir depend on that.  That eliminates a bug
where 'cleandir' in a directory which included e.g. bsd.prog.mk but which
also had subdirs would 'make clean' all the subdirs and then 'make cleandir'
all ofthe subdirs.  It also allows Makefiles to add more dependencies
to 'clean' after inclusion of the make template.

If 'clean' is already defined, the behaviour is the same as it used to be.

libraries with LD, but add /usr/lib/crtbegin.o and /usr/lib/crtend.o
before and after the rest of the stuff being linked.  This is a losing
situation all-around: for correct 'DESTDIR' builds, it should be including
them from ${DESTDIR}/usr/lib.  However, since those objects should be
included for all shared libraries, including them from ${DESTDIR} won't work,
because they won't be installed by normal builds by the time they need to
be used.

c238d2b94e Add the ability to override defaults in bsd.own.mk more easily, by 
looking for "${MAKECONF}", or failing that, "/etc/mk.conf" and including
the first one it finds, if it exists.  From Chris Demetriou <cgd@netbsd.org>,
PR #1970.

5eb08a6790 Get the current working directory from "/bin/pwd" rather than "pwd". 
Changes to the shell make the behavior of "make obj" inconsistent
with previous behavior, depending on the login shell used by the user.
See PR #2200 for details.  PR remains open while further analysis is
done.  This at least restores the previous semantics for us csh(1) users.

4297bc2d3a don't include the .c.a rule on the alpha. see p.r. 1488 for an 
example of how make breaks when it's present.  In particular, it causes
build of the compiler toolchain to fail if present, which keeps
a complete system from building, on the alpha.

d136b73088 show the directory depth, by printing out the hierarchy name. 
Suggested by Ty Sarna, implemented by me.  Useful, because it tells you
how deep you are, and allows you to paste the pathname in to 'cd' to the
directory.
