Re: [rfa/rfc] Build libcommon.a for gdb and gdbserver

Yao> Add some more targets in common/Makefile.in in this patch.  `make
Yao> {info,pdf,html,dvi}' works.

This patch changes gdb/common/ to use Automake.  The advantages of using
it are simpler maintenance and more features.  E.g., the above bug would
not have occurred; the Makefile you actually edit is just 4 lines of
code; dependency tracking is built in; etc.

I didn't deal with COMMON_CPU_{SRC,OBJ} in this patch.  I wasn't sure if
these were placeholders or leftovers from something else.

Let me know what you think.  I am running it through the tester.
