>Description:
	bsd.lib.mk adds a link to /usr/obj/build/usr/lib for all libraries
	which don't have their own lib*.*: lines in their Makefile.

cd /usr/obj/build/usr/lib
ls -l | grep -v "src/lib" | grep -v "src/gnu/lib/" | grep -v "src/gnu/usr.bin/gcc/lib"

libbfd.a -> /home/source/obj_i386/src/gnu/usr.bin/gdb/bfd/libbfd.a
libbib.a -> /home/source/obj_i386/src/gnu/usr.bin/groff/libbib/libbib.a
libcc1.a -> /home/source/obj_i386/src/gnu/usr.bin/gcc/common/libcc1.a
libdhcp.a -> /home/source/obj_i386/src/usr.sbin/dhcp/common/libdhcp.a
libdriver.a -> /home/source/obj_i386/src/gnu/usr.bin/groff/libdriver/libdriver.a
libgroff.a -> /home/source/obj_i386/src/gnu/usr.bin/groff/libgroff/libgroff.a
libiberty.a -> /home/source/obj_i386/src/gnu/usr.bin/gdb/libiberty/libiberty.a
librcs.a -> /home/source/obj_i386/src/gnu/usr.bin/rcs/lib/librcs.a
libreadline.a -> /home/source/obj_i386/src/gnu/usr.bin/gdb/readline/libreadline.a
libunix.a -> /home/source/obj_i386/src/gnu/libexec/uucp/libunix/libunix.a
libuuconf.a -> /home/source/obj_i386/src/gnu/libexec/uucp/libuuconf/libuuconf.a
libuucp.a -> /home/source/obj_i386/src/gnu/libexec/uucp/libuucp/libuucp.a

>How-To-Repeat:
	Build a system with obj dirs and then build a kernel in
	/usr/obj/src/sys/arch/<arch>/compile/<xxx> and watch the output:

[..]
building standard compat library
install -d /usr/obj/build/usr/lib
/usr/obj/build/usr/lib/libcompat.a -> /home/source/obj_i386/src/sys/arch/i386/compile/VEEGO/lib/compat/libcompat.a
ranlib libcompat.a
[..]

Bumm. The kernel build overwrittes the old link for libcompat.a and now you
have a real problem to link programms from the NetBSD src-tree with -lcompat.

cd /usr/obj/build/usr/lib; ls -la | grep libcompat.a
- before the kernel build:

libcompat.a -> /home/source/obj_i386/src/lib/libcompat/libcompat.a

- after the kernel build:

libcompat.a -> /home/source/obj_i386/src/sys/arch/i386/compile/VEEGO/lib/compat/libcompat.a

>Fix:
	Only link libraries to ${BUILDDIR}${LIBDIR}/ which will be
	installed to /usr/lib.
	One solution will be a FLAG in the Makefile of this libraries
	and use that in bsd.lib.mk.
