Mike Frysinger 7e3941ac06 gdb/gdbserver: switch to AC_CONFIG_MACRO_DIRS
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.

dnl NB: When possible, try to avoid explicit includes of ../config/ files.
dnl They're normally found by aclocal automatically and recorded in aclocal.m4.
dnl However, some are kept here explicitly to silence harmless warnings from
dnl aclocal when it finds AM_xxx macros via local search paths instead of
dnl system search paths.
dnl gdb/gdbserver/configure.in uses BFD_HAVE_SYS_PROCFS_TYPE.
m4_include(../bfd/bfd.m4)
dnl This gets AM_GDB_WARNINGS.
m4_include(../gdbsupport/warning.m4)
dnl codeset.m4 is needed for common.m4, but not for
dnl anything else in gdbserver.
