The way the common code is built is currently kind of weird and ugly.
Even though the code is shared, there's still places you have to do
the same work twice, for example if you add a new .c or .h file to
common, for example, you have to add it to both GDB's and gdbserver's
Makefiles.  If you add stuff that needs configure checks, you have to
add those twice too.  Also we build gnulib twice.  Also, the way the
compiler is invoked means that you can accidentally #include GDB- or
gdbserver-specific headers in common code.  It's all very error-prone. 

For the future we'd like to move the common code into its own toplevel
directory with it's own Makefile, it's own ./configure, etc.  It would
be built once, to a libgdbcommon.a or something that GDB and gdbserver
would statically link.  We can't do that if gdb/{common,nat,target}
have conditional code.
