Subject: 	* configure: Move gcc_version_trigger stuff from here...
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ae831be502bf99bc5da6b755f1d63a4dcea753c9;p=binutils-gdb.git

	* configure: Move gcc_version_trigger stuff from here...
	* configure.in: ...to here.

	* configure.in: Separate subconfigure options added by this file from
	options given by the user.  Add machinery to put args for host
	subconfigures into the Makefile.

	* Makefile.tpl: Remove 'vault' targets.
	* Makefile.tpl: Reorder and comment dependencies.
	* Makefile.in: Regenerate.
