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).

Projects no longer need to specify LLVM_OBJ_ROOT.  Also, for the prdirs target, don't let make print out all of the echo commands before the echos get echo'd

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.

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).
