Great, that worked, thanks. For a future release though, think that
DESTDIR could be supported? It shouldn't be that difficult, all that
would need to be changed is in Makefile.config.in:
PROJ_prefix := $(DESTDIR)@prefix@
PROJ_bindir := $(DESTDIR)@prefix@/bin
PROJ_libdir := $(DESTDIR)@prefix@/lib
PROJ_datadir := $(DESTDIR)@prefix@/share
PROJ_docsdir := $(DESTDIR)@prefix@/docs/llvm
PROJ_etcdir := $(DESTDIR)@prefix@/etc/llvm
PROJ_includedir := $(DESTDIR)@prefix@/include
PROJ_infodir := $(DESTDIR)@prefix@/info
PROJ_mandir := $(DESTDIR)@prefix@/man
And then the makefile would be (more) gnu-compliant, and make linux
packaging much more simple and straightforward.

So does that mean that if we're doing a pure llvm, or llvm + llvm-gcc4,
we can just do "make" and not "make tools-only"?

We hope to add http://felix.sourceforge.net to that list :) It currently
is backed by a c++ generator, but we'd like to branch out to our own
