Remove kernbb(8) from the source tree.

It's been broken for several years and with all the binutils/toolchain
changes in flight, it might make more sense to put efforts into dtrace and
hwpmc instead.

-.Dt KERNBB 8
-.Os
-.Sh NAME
-.Nm kernbb
-.Nd generate a dump of the kernels basic-block profile buffers
-.Sh SYNOPSIS
-.Nm
-.Sh DESCRIPTION
-The
-.Nm
-utility is used to extract the basic-block profiling buffers of the running
-kernel into the files needed for the
-.Xr gcov 1
-tool.
-.Pp
-At least one source file in the running kernel must have been compiled
-with the
-.Fl Fl test-coverage
-and
-.Fl Fl profile-arcs
-options.
-.Pp
-The output is stored in the filenames compiled into the kernel by
-.Xr gcc 1 .
-If the absolute pathname cannot be written to, the directory part
-of the filename is discarded and the file stored in the current
-directory under its basename.
-.Pp
-The output files are named
-.Pa *.da ,
-and the
-.Xr gcov 1
-program will extract the counts and merge them with the source
-file to show actual execution counts.
-.Sh FILES
-.Bl -tag -width /boot/kernel/kernel -compact
-.It Pa /boot/kernel/kernel
-the default system
-.It Pa /dev/kmem
-the default memory
-.El
-.Sh SEE ALSO
-.Xr cc 1 ,
-.Xr gcov 1
-.Sh AUTHORS
-The
-.Nm
-utility was written by
-.An Poul-Henning Kamp ,
-along with the kernel-support.
-.Sh BUGS
-There are far too much magic and internal knowledge from GCC in this.
