Moved Makefile.common to Makefile.rules. This makes project Makefiles easier
to support, and allows for easier overriding of default configuration values
that used to be in Makefile.common.
Modified Makefile.config.in to determine paths for directories (like
LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this
works better for symbolic links).

and explicitly declare all the ones we're using for LLVM.
This quickly cancels many of GNU Make's implicit rules and reduces build time.
The only caveat is that any new suffixes may need to be explictly added to
the .SUFFIXES pseudo target.
Removed the -only-static option as it is no longer used.

broken by libtoolification anyways, and noone can use it because purify doesn't
support the 64-bit sparc compilers even if it weren't broken!

the pre-release 1.1 branch and pre-release 1.1.1).
Made the USE_SPEC option work.
Silenced unnecessary error output from the cmp command when checking for
updates to lex/yacc generated files. This fixes a problem where we get error
messages the first time the file is generated.
Fixed the distclean option. It is now in the Makefile (i.e. only runs in the
top level source directory), removes more files, and plays nicely with
external project Makefiles.

The shell AND/OR operators short-circuit on command success/failure, which is
the inverse of exit status (i.e. 0 means success, non-zero means failure).

o Not all versions of diff have the -q option
o The cmp program is probably faster than diff
Fixed the logic that only copies the file over if no differences are found.

hide the bison command line.
* If running flex or bison gives us the files we already have, don't overwrite
the ones we have, which cause unnecessary compilation. I demand the ability
to make meaningless changes without penalty!

do the following:
1) Determine their default values without $HOME
2) Configure the default values as full absolute pathnames.
This should help fix the nightly test builds.

of the llvm source directory.
The main modification was to add new environment variables: one set for llvm
entities and another set for source entities current being compiled.
This should make the Makefile more flexible and easier to understand as each
environment variable only does one thing.
