files that USE the .inc file unless the contents of the .inc file changes.
This should fix the problem where reconfiguring causes all targets to be
completely rebuilt (because config.h is usually modified, causing libsystem
to be rebuilt, causing tblgen to be rebuilt, causing .inc files to be
rebuilt, causing .o files to be rebuilt).
This patch also checks in a gross hack where .o files now explicitly depend
on $(BUILT_SOURCES), to avoid problems where the .inc files are not completely
generated before the .o files start to compile.

to BUILD_OBJ_SRC. This will save the config.status and mklib files, then
wipe out the BUILD_OBJ_ROOT, copy back config.status and mklib, and then
run config.status to regenerate the makefiles. This target gives you a
completely clean/fresh BUILD_OBJ_ROOT.

specify where the bytecode library is to be installed. This allows the
default location ($prefix/lib) to be overridden, for special case runtime
libraries like the cfe runtime libs.

present in a directory that LLVM normally builds, it will skip building
the directory entirely. This is useful for allowing a bunch of projects to
live in the source tree but not be compiled from time to time.

* Implement the FAKE_SOURCES feature for GCCLibraries/crtend \
* Search for distribution files >first< in srcdir and >second< in objdir \
* Make dist-hook only run in top level directory. \
* Make dist-check run correctly in parallel builds \
* Wrap lines to 80 cols \
* Standardize variable names

Change construction of bytecode libraries from producing a single bytecode
file to producing a library containing bytecode files. This gets around the
problem of multiple symbol definitions in the linker if something like
-lc -lc is attempted on the command line. Previously this happened because
the linker would find libc.bc as a "library". It will now find libc.a which
it can simply search for missing symbols instead of linking in wholesale.

* Get rid of appending -lbz2 and -lz to ExtraLibs now that we don't need
them any more.
* Fix the dist-check target so that EXTRA_DIST can be defined AFTER the
include of Makefile.common. This is needed because Makefile.common
provides variable definitions that may need to be used in computing the
value of EXTRA_DIST.
* Clean up some "distdir" target output.

Tools and libraries will be built into $(BUILD_OBJ_ROOT)/$(BuildMode)/bin and \
$(BUILD_OBJ_ROOT)/$(BuildMode)/lib, respectively. Furthermore, the example \
programs will go in $(BUILD_OBJ_ROOT)/$(BuildMode)/examples to keep them \
separate from the tools and hopefully out of the PATH. Install targets \
have not changed.

* Don't include Makefile.rules in set of preconditions, it never has to be
copied to objdir.
* Enable the "update makefile first before executing targets" feature in
gnu make by *not* using a full path to the Makefile in the rule.

$(ObjDir) and clean out all build modes (Debug, Release, Profile) in
addition to the normal "clean" rules.
* Fix "clean" problems with Lex/Yacc so all files are remove properly.
* Ensure errors from "rm" don't thwart the uninstall and clean targets.

sub-makes and recursively append causing huge command lines and incorrect
compilation results.
Also, fix the printvars target to align its output and ensure that the
contents of variables can't get interpreted by the shell.
