(toplevel patch) Configure host subdirs in Makefile, optionally.

(toplevel patch) Configure host subdirs in Makefile, optionally.

[Nathanael Nerode]

Update of http://gcc.gnu.org/ml/gcc-patches/2002-11/msg01885.html

Tested on i686-pc-linux-gnu.  This doesn't configure in
the Makefile by default, so it's pretty safe.  I'll do that a bit later. :-)

	* Makefile.tpl: Add targets for configuring host subdirs in Makefile,
	and corresponding dependencies.
	* Makefile.in: Regenerate.

Something is line-wrapping you...

Ideally we would build binutils/gas/ld before configuring GCC, I think. 
We try to use them in the configure script; right now this is avoided
by getting the version number out of the source tree if they're in-tree
but that detail could be cleaned up if they were built in advance.
