	When build != host, create libiberty for the build machine.

	* Makefile.in (TARGET_CONFIGARGS, BUILD_CONFIGARGS): Replace
	CONFIG_ARGUMENTS.
	(ALL_BUILD_MODULES_LIST, BUILD_CONFIGDIRS, BUILD_SUBDIR):
	New variables.
	(ALL_BUILD_MODULES, CONFIGURE_BUILD_MODULES): New variables
	and rules.
	(all.normal): Depend on ALL_BUILD_MODULES.
	(CONFIGURE_TARGET_MODULES rule): Use TARGET_CONFIGARGS.
	(all-build-libiberty): Depend on configure-build-libiberty.

	* configure: Calculate and substitute proper value for
	ALL_BUILD_MODULES.
	* configure.in: Create the build subdirectory.
	Calculate and substitute TARGET_CONFIGARGS (formerly
	CONFIG_ARGUMENTS); also BUILD_SUBDIR and BUILD_CONFIGARGS (new).

libiberty:
2001-11-27  Zack Weinberg  <zack@codesourcery.com>

	* _doprnt.c: Moved here from gcc/doprint.c.  Adjust to build
	in libiberty context.  Fix typo in leading comment.
	* configure.in: Fix various AC_DEFINEs so autoheader works.
	If any of vprintf, vsprintf, vfprintf is missing from libc,
	then AC_REPLACE_FUNCS(_doprnt).
