* config.host: New file.

	* config.gcc: Remove some host-specific stuff and some
	logic needed only for repeated invocation.
	* configure.in: Use config.host.
	* configure: Regenerate.

+# This is the GCC host-specific configuration file
+# where a configuration type is mapped to different system-specific
+# definitions and files.  This is invoked by the autoconf-generated
+# configure script.  Putting it in a separate shell file lets us skip
+# running autoconf when modifying host-specific information.
+
+# This file switches on the shell variable ${host}.  As much of this as
+# is reasonable should be replaced with autoconf tests in the future.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  host_xm_file         List of files to include when compiling for the
+#                       host machine.
+#
+#  host_xm_defines      List of macros to define when compiling for the
+#                       host machine.
+#
+#  host_xmake_file      List of host-specific makefile-fragments.
+#
+#  host_exeext          Set to the suffix, if the host machine requires
+#                       executables to have a file name suffix.
+#
+#  host_extra_objs      List of extra host-dependent objects that should
+#                       be linked into the compiler proper.
+#
+#  host_extra_gcc_objs  List of extra host-dependent objects that should
+#                       be linked into the gcc driver.
+#
+#  out_host_hook_obj    An object file that provides the host hooks.
+
+# When setting any of these variables, check to see if a corresponding
+# variable is present in config.build; if so, you will likely want to 
+# set it in both places.
+
