Yaroslav Tykhiy 0c35219978 Don't forget to set MAKEFLAGS in the childs' environment
from the .MAKEFLAGS global variable even if it's empty or
unset.  This means setting MAKEFLAGS to just an empty string
in the latter case.

If not doing so, make(1) behaved inconsistently WRT MAKEFLAGS.
In particular, it would let a `-f foo' option down to sub-makes
if .MAKEFLAGS was unset.  E.g.,

	env MAKEFLAGS="-f mymakefile" make

would pass `-f mymakefile' down to sub-makes via their environment
(unless mymakefile added something to .MAKEFLAGS).
But any additional options appearing would change this behaviour to
not passing `-f mymakefile' to sub-makes, as in:

	env MAKEFLAGS="-f mymakefile" make -D DUMMY

or

	env MAKEFLAGS="-f mymakefile -D DUMMY" make

(unless mymakefile cleared .MAKEFLAGS).

Also make(1) would leave MAKEFLAGS at its initial value if the
makefile set .MAKEFLAGS to an empty value.  I.e., it was impossible
to override MAKEFLAGS with an empty value.  (Note well that makefiles
are not to touch MAKEFLAGS directly, they alter .MAKEFLAGS instead.
So make(1) can filter out things such as -f when copying MAKEFLAGS
to .MAKEFLAGS at startup.  Direct modifications to MAKEFLAGS just go
nowhere.)

While the original intentions of the BSD make authors are somewhat
unclear here, the bug proves that NOT passing -f options down is
the settled behaviour because the opposite behaviour is totally
unreliable in the presence of any other options.  In addition, not
passing down -f's found in the environment is consistent with doing
so WRT the command line.

Update the manpage accordingly and make the whole description of
MAKEFLAGS and .MAKEFLAGS more consistent as this change indeed
brings more consistency into the reliable behaviour of make(1).

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The ``world''
target should only be used in cases where the source tree has not
changed from the currently running version.  See:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The ``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/<arch>/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
