--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time. Currently it only
turns on _GLIBCXX_DEBUG. Other expensive debugging checks added later
should be controlled by this configure option.
This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.

Enable the makefile check on the result of find-cycles.pl. LLVM is now
cycle free and we intend to keep it that way. This patch will fail the
build if cycles are found.

have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.
Patch contributed by Anton Korobeynikov. Thanks!

dependency is found. The find-cycles.pl script now exits with a return code
that equals the number of cycles found. The Makefile was changed to ignore
the status code of find-cycles.pl. This should be removed once the libraries
are free of cyclic dependencies.

Don't check in the LibDeps.txt and FinalLibDeps.txt files to CVS because
the content differs from platform to platform. Instead, adjust the makefile
so that a dummy llvm-config is built if Perl is not available.

1. If Perl is not available, don't run Perl dependent targets.
2. Check in FinalLibDeps.txt for build environments that can't build it
because there's no Perl processor.
3. Ensure that FinalLibDeps.txt depends on LibDeps.txt so it is
automatically regenerated.
4. Support objdir != srcdir building.
