peter b5e718b143 libstdc++.so breaks on amd64 due to bogons in our build, so prevent the
shared library being built for amd64.  The problem is that libstdc++.so
is produced with 'cc -shared'.  This has an internal -lgcc, which is
not PIC.  libstdc++.so uses exceptions and the dwarf2 unwinder, which
are in libgcc.a.  As a result, non-PIC code gets pulled into libstdc++.so.
This is fatal on amd64 when certain relocation types cannot be used in
PIC mode.  The official FSF solution to this is to have libgcc.so with
internal ELF symbol versioning to solve the ABI problem, but I dont want
to fight that battle yet.  I tried making libgcc_pic.a (which worked
fine), but thats not something for the 11th hour before a release.

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
``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.
