No need for patches.  My build of gcc trunk finally finished:

	$ ./configure --prefix=$HOME/opt/gcc \
		CFLAGS_FOR_TARGET="-g -O2 -B/usr/lib/x86_64-linux-gnu" \
		CXXFLAGS_FOR_TARGET="-g -O2 -B/usr/lib/x86_64-linux-gnu"
	$ make FLAGS_FOR_TARGET='-B$(build_tooldir)/bin/ '\
'-B$(build_tooldir)/lib/ -isystem $(build_tooldir)/include '\
'-isystem $(build_tooldir)/sys-include '\
'-B/usr/lib/x86_64-linux-gnu' \
		BOOT_CFLAGS="-g -O2 -B/usr/lib/x86_64-linux-gnu"
	$ make FLAGS_FOR_TARGET='-B$(build_tooldir)/bin/ '\
'-B$(build_tooldir)/lib/ -isystem $(build_tooldir)/include '\
'-isystem $(build_tooldir)/sys-include '\
'-B/usr/lib/x86_64-linux-gnu' \
		BOOT_CFLAGS="-g -O2 -B/usr/lib/x86_64-linux-gnu" \
		install

The resulting compiler even seems to work, as long as you pass
-B/usr/lib/x86_64-linux-gnu to it.

Yes, it ought to be easier.  Maybe FLAGS_FOR_TARGET does everything we
need.  I'd be happy to review a patch that teaches configure.ac to
handle something like

	$ ./configure --prefix=$HOME/opt/gcc \
		--extra-flags-for-target=-B/usr/lib/x86_64-linux-gnu \
		BOOT_FLAGS='-g -O2 -B/usr/lib/x86_64-linux-gnu'
	$ make
	$ make install

I'd be interested in the answer to this if there is one, too.

Thanks, Sedat.
