gdb/gdbserver: switch to AC_CONFIG_MACRO_DIRS

Browse source 
These dirs don't use automake, so use AC_CONFIG_MACRO_DIRS to specify
../config as a search dir for m4 macros.  This allows removal of a lot
of hand-written m4_include's from acinclude.m4 files, and simplifies
use of `aclocal` or `autoreconf` as manual -I is not needed.
