[PATCH] Fix toplevel configure for --target TARGET_NAME etc.

[Jakub Jelinek]

Hi!

autoconf supports lots of ways to specify --target etc. arguments,
but with the current toplevel configure only --target=TARGET_NAME
works. If one uses e.g. --target TARGET_NAME, -target=TARGET_NAME,
--t TARGET_NAME etc., it fails badly (e.g. when not using =
but whitespace to separate the option from its optarg, baseargs
contains trailing --target (TARGET_NAME is wiped out), so whatever
comes after ${BUILD,HOST,TARGET}_CONFIGARGS in invocation of some command
is treated as --target's optarg.
The following patch fixes it.
Ok to commit?

	* configure.in (baseargs): Remove all supported forms of
	--cache-file, --srcdir, --host, --build and --target options
	from argument lists.
	* configure: Rebuilt.
