right so there is no need to duplicate logic, just use the values the makefile
provides.
Eliminate some redundnt -D options from the output.
Fix the help output so it fits on 80 cols.

--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.

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!

1. llvm is built with objroot = OBJ and installed.
2. OBJ is deleted or install tree is shipped.
3. llvm-config is run.
In this scenario, llvm-config shouldn't emit an error message at #3, it
should just know it's not running in the objdir :)

If installed, ignore the prefix the tree is configured with: always use the
prefix that llvm-config is currently at, which may be different if the tree
was moved.
