These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.

Move the implementation of the fix from Makefile.rules to Makefile. This
ensures that it is only checked on a top-level rebuild, and not in every
single subdirectory. This removes some annoying messages from the build and
numerous executions of config.status if the .in file changes but not
substantively enough to cause the .h file to be modified by config.status.

Make any header files that are automatically generated be preconditions of
the compilation. This ensures that if a *.h.in file is changed then its
corresponding *.h file gets updated on the next rebuild. Note that this can
lead to confusing (but correct) results if the *.h.in file changed
unsubstantially so that autoheader doesn't update the *.h file. In that case,
manually touch the *.h file in question to restore order. Moral of the story,
if you're going to "touch" a *.in file then modify it substantially.

1. Allow DIST_CHECK_CONFIG_OPTION to specify a set of options to be passed
to the configure script during the dist-check target. This allows things
to be passed down on a project basis so the configure doesn't fail.
2. Use the tar | (cd ; tar ) idiom to copy files which is more flexible
than using the cp command. THis allows us to exclude CVS .svn
directories at source rather than stripping them out of the tar ball.

llvm archive or re-linked libraries:
1. Permit the "JIT" special keyword on LLVMLIBS to be recognized when
building a library, not just for building tools
2. If LINK_LIBS_IN_SHARED is set, the LLVMLIBS and USEDLIBS can be specified
when linking a shared library and the libraries listed will be
incorported into the shared library. THis is only used when the
SHARED_LIBRARY variable is set.

* Consolidate all "install" usage to the install program/script found by
autoconf which includes the autoconf/install-sh script if necessary
* Change Makefile.rules to not use the -D flag to install but use the
MKDIR command as necessary.
* Change Makefile.rules to differentiate between installation of executable
files and regular data files to get the permission modes correct.

* Make it possible to have the Install program run in verbose mode when
the TOOL_VERBOSE=1 option is set
* Ensure non-executable installed files do not install with execute perms.

When llvm-gcc is not available, bypass rules for Modules and Bytecode
Libraries that require llvm-gcc and emit instead a warning that llvm-gcc
is not available. This permits "make LLVMGCC=" to build LLVM completely
without error and provides warnings about the modules and bc libs that
could not be constructed.

* Rename BUILD_* to PROJ_*
* Differentiate between LLVM's Makefile.conf and the project's
* Use project specific install locations

passes the -module option on the libtool command line to ensure that the
shared library being built can be dlopened and dlsym can work on that
module. LOADABLE_MODULE should be sent only in conjunction with the
SHARED_LIBRARY directive. It should generally be used for any module that
is intended to be the target of an LLVM -load option. Note that loadable
modules will not have the lib prefix but otherwise look like shared
libraries. This is per the libtool recommendations and prevents these
special shared libraries from being linked in via -l option to the linker.

Reverting the quote patch. For some reason, this breaks the building of
llvm/runtime (the shell doesn't like it for some reason). I might play
with it to see if I can get the quotes done in such a way that the shell
like it, but no promises.

Many thanks to Duraid Madina for doing the heavy lifting on the analysis
of this problem.

* When reconfiguring, make sure the config.cache file is blown away so that
its (old) values don't short-circuit doing the tests. When a reconfigure
is done, it should be done from scratch, without the cache.
* For dist-check, don't pass --with-llvmgccdir any more because configure
doesn't have this option any more.

* Cleanup LLVMGCXX and LLVMGCC by providing LLVMGXXWITHPATH and LLVMGCCWITHPATH
variables that add the $(LLVMToolDir) to the path so the CFE tools can find
the right LLVM tools they depend on.
* Standardize the name of a variable: cferuntime_libdir -> CFERuntimeLibDir
