I now remember why we did this .. because autoconf gets it wrong.

Using the autoconf names for these variables, we get the following expansions:

PROJ_bindir     := $(DESTDIR)/proj/llvm/install-3/progs
PROJ_libdir     := $(DESTDIR)${exec_prefix}/lib
PROJ_datadir    := $(DESTDIR)${datarootdir}
PROJ_docsdir    := $(DESTDIR)${datarootdir}/doc/${PACKAGE_TARNAME}
PROJ_etcdir     := $(DESTDIR)${sysconfigdir}
PROJ_includedir := $(DESTDIR)${prefix}/include
PROJ_infodir    := $(DESTDIR)${datarootdir}/info
PROJ_mandir     := $(DESTDIR)${datarootdir}/man
PROJ_datarootdir:= $(DESTDIR)${prefix}/share

This is invalid syntax for makefiles. I don't know why autoconf can't resolve
its variable names on its own.

Consequently, I'm not going to "fix" this. If someone wants to patch autoconf to
get this right then I might consider making the change. Perhaps when we upgrade
our autoconf version it will just magically fix itself.
