always using `=' for an option with an argument. Pass a presumed
--host or --target explicitly.

Canadian Cross, use plausible default values for numerous

them, based on either an existing Makefile or on searching for gcc
in PATH. Substitute for CC and CXX in Makefile.
* configure.in: Remove libm from target_libs. Separate
target_configdirs from configdirs. If CC is not set in
environment, try to get it from a host Makefile fragment. Rewrite
changes of configdirs to use skipdirs instead. A few minor
tweaks. Take directories out of target_configdirs as they are
taken out of configdirs. Remove existing Makefile files from
subdirectories. Substitute for TARGET_CONFIGDIRS and
CONFIG_ARGUMENTS in Makefile.
* Makefile.in (TARGET_CONFIGDIRS): New variable, automatically set
by configure.in.
(CONFIG_ARGUMENTS): Likewise.
(CONFIGURE_TARGET_MODULES): New variable.
($(DO_X)): Loop over TARGET_CONFIGDIRS as well as SUBDIRS.
($(CONFIGURE_TARGET_MODULES)): New target.
(configure-libg++, configure-libio): New targets.
(all-libg++): Depend upon configure-libg++.
(all-libio): Depend upon configure-libio.
(configure-libgloss, all-libgloss): New targets.
(configure-libstdc++): New target.
(all-libstdc++): Depend upon configure-libstdc++.
(configure-librx, all-librx): New targets.

* configure.in: Remove SunOS patch suffix removal hack.
* configure: Delete SunOs patch suffix from host_canonical

* configure.in: Add comments to patch suffix removal for easier

add support for --without (and add this to the usage message); also
explicitly add a --host=${host_alias} to the command line when

screws nested configures. "unset PWD" is the right answer, except that
Decstation sh doesn't *have* unset.
Note also that the send-pr build will fail if you have PWD in your
environment, because emacs also (foolishly) trusts it.
* configure: just set PWD=`pwd` at the top, since Ultrix sh
doesn't have unset and all success paths (and most error paths)
out set it anyway. (Note: should change all uses of ${PWD=`pwd`}
to just ${PWD} to avoid confusion.)
