Add a WITH_CLANG_EXTRAS option for src.conf(5), disabled by default,

that builds the following additional llvm/clang tools:

- bugpoint
- llc
- lli
- llvm-ar
- llvm-as
- llvm-bcanalyzer
- llvm-diff
- llvm-dis
- llvm-extract
- llvm-ld
- llvm-link
- llvm-mc
- llvm-nm
- llvm-objdump
- llvm-prof
- llvm-ranlib
- llvm-rtdyld
- llvm-stub
- macho-dump
- opt

These tools are mainly useful for people that want to manipulate llvm
bitcode (.bc) and llvm assembly language (.ll) files, or want to tinker
with llvm and clang themselves.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBllvm-as\fR is the \s-1LLVM\s0 assembler.  It reads a file containing human-readable
+\&\s-1LLVM\s0 assembly language, translates it to \s-1LLVM\s0 bitcode, and writes the result
+into a file or to standard output.
+.PP
+If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR reads its input from
+standard input.
+.PP
+If an output file is not specified with the \fB\-o\fR option, then
+\&\fBllvm-as\fR sends its output to a file or standard output by following
+these rules:
+.IP "\(bu" 4
+If the input is standard input, then the output is standard output.
+.IP "\(bu" 4
+If the input is a file that ends with \f(CW\*(C`.ll\*(C'\fR, then the output file is of
+the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR.
+.IP "\(bu" 4
+If the input is a file that does not end with the \f(CW\*(C`.ll\*(C'\fR suffix, then the
+output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR
+suffix is appended.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Enable binary output on terminals.  Normally, \fBllvm-as\fR will refuse to
+write raw bitcode output if the output stream is a terminal. With this option,
+\&\fBllvm-as\fR will write raw bitcode regardless of the output device.
+.IP "\fB\-help\fR" 4
+.IX Item "-help"
+Print a summary of command line options.
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+Specify the output file name.  If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR
+sends its output to standard output.
+.SH "EXIT STATUS"
+.IX Header "EXIT STATUS"
+If \fBllvm-as\fR succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value.
